Start by whipping the fat until it looks airy. Add the masa harina or fresh masa in turns with broth, and keep mixing until the dough is thick enough to spread.
A small dollop of finished dough floats in water when enough air is trapped in it, and that air is what makes a tender tamal.
The corn itself has been nixtamalized. You either buy it fresh from a tortilleria or rehydrate dried masa harina, and the fat is usually lard or shortening.
Published fat ratios differ by more than a factor of two. Per cup of masa harina, Hola Jalapeno (2023) uses about 1/6 cup of fat and Rick Bayless (2023) about 3/8 cup, so texture decides when the dough is finished.
Fresh masa, masa harina or masa preparada: which one to use
Unprepared fresh masa from a tortilleria is the traditional choice. Masa harina labeled for tamales is the reliable stand-in when you can’t get fresh.
Nixtamalized corn dough gets whipped with fat and broth, plus baking powder for lift, and steams into a soft, tender tamal. That whipped dough is what people mean by masa for tamales.
Masa harina is the same dough dried and powdered (Everyday Southwest), and fresh masa is simply that dough before it gets dried.
Rick Bayless, in his Exploring Mexico’s Kitchen episode on tamales (2023), says the best tamales start with fresh-ground masa and fresh-rendered pork lard. Even so, his basic tamal dough recipe (2023) counts 4 cups (2 pounds) of fresh masa as equal to 3 1/2 cups of masa harina stirred into 2 1/4 cups of hot water.
| Form | Texture | What to add | Where to find it |
|---|---|---|---|
| Fresh unprepared masa (masa sin preparar) | Moist, coarse-ground dough | Lard, broth, baking powder, salt | Tortilleria or Latin grocer, usually marked S |
| Masa preparada | Dough with lard and salt already mixed in | Sources disagree, so test first | Same shops, usually marked P |
| Masa harina for tamales | Dry, coarse-ground flour | Hot water or broth, fat, baking powder, salt | Supermarkets and online |
Cooks split on masa preparada. Muy Bueno says you can use it as it comes and just add flavor. Hola Jalapeno (2023) says it still needs more broth and usually more lard and baking powder.
Taste it and check the texture before adding anything.
How tamale masa differs from tortilla masa
Same corn, different recipe, and tamale masa carries far more fat.
Tortilla masa is masa harina, water and salt (Muy Delish). Tamale masa starts from that base and adds whipped fat and broth along with baking powder, and the grind is usually coarser.
Bayless calls for coarse-ground masa in his tamal dough. Maseca sells a separate Tamal flour, described on its listing as a white corn flour with a coarse grind made for tamales.
The corn behind both doughs is soaked in limewater (calcium hydroxide, sold as cal), rinsed, hulled and ground, as Muy Bueno describes it. Muy Bueno’s author recalls her grandmother grinding nixtamal on a metate, while today a tortilleria does the grinding.
Pupusas start from the same nixtamalized corn, but making masa for pupusas follows its own method.
Choosing a masa harina brand and label
Maseca’s own listing describes its Tamal flour as coarse-ground white corn masa designed for tamales. Other sources don’t agree on whether to buy it.
Isabel Eats (2019) says to buy original Maseca in the white bag, not the tamale bag. Mama Maggie’s Kitchen (2020, updated 2026) says the reverse: buy masa harina marked for tamales, and blame grainy masa on the wrong flour.
Muy Bueno prefers Maseca and also likes Bob’s Red Mill, King Arthur and Masienda. Hola Jalapeno (2023) favors Masienda, Bob’s Red Mill and King Arthur, especially non-GMO or heirloom corn.
The ratio of fat to masa harina changes from brand to brand, so the package directions come first (Everyday Southwest). Maseca’s Tamal bag gives 4 cups of flour, 3 cups of warm water, 1 cup of lard, 1 1/2 teaspoons of salt and 1 tablespoon of baking powder.
The easy route is to buy the bag that says tamales and follow its directions, then adjust by texture.
Lard, shortening or oil: which fat gives the lightest masa
Lard is the traditional fat and shortening is the safest swap. Oil works in some recipes and fails in others, depending on the masa.
Lard (manteca)
Lard gives the most authentic flavor and a rich, tender crumb (Mama Maggie’s Kitchen), and fresh-rendered pork lard is the fat Bayless pairs with fresh masa. The catch is that rendered lard needs less broth than the shelf-stable kind, so a recipe written for one shifts with the other (Muy Bueno).
It also rules out vegetarian tamales.
Vegetable shortening
Shortening whips up light and fluffy and spreads easily (Mama Maggie’s Kitchen), and her recipe uses it at the same quantity as lard. It just doesn’t taste like real lard.
Oil
Isabel Eats (2019) makes 45 to 50 masa harina tamales with canola oil and describes the dough as soft without being greasy. Maseca’s own tamale recipe uses cooking oil too, and its Tamal package says corn oil can replace lard.
Hola Jalapeno (2023) reports no success with liquid fats in masa harina dough, though they work in fresh masa. Olive oil changes the flavor of the tamale (Isabel Eats, Mama Maggie’s Kitchen), and any strongly flavored oil carries into the finished tamal.
So the sources split on oil with masa harina. Two published recipes (Isabel Eats and Maseca) use it, and one chef-author reports it failing.
Butter and coconut oil appear as substitutes too (Hola Jalapeno). Mama Maggie’s Kitchen warns that coconut oil flavors the tamale.
My rule of thumb is lard or shortening with masa harina and a neutral oil with fresh masa. If oil is all you have, go with Maseca’s oil recipe.
How much fat, broth, salt and baking powder does masa for tamales need?
No two published recipes agree, but they cluster. Per cup of masa harina, expect about 1/6 to 3/8 cup of fat, 3/4 to 1 1/3 cups of liquid, 3/8 to 3/4 teaspoon of salt and 1/3 to 1 teaspoon of baking powder.
Those ranges are worked out from each recipe’s own quantities, taken from Isabel Eats (2019), Mama Maggie’s Kitchen (2020, updated 2026), Rick Bayless (2023), Hola Jalapeno (2023) and Maseca’s Tamal package directions.
Fat runs from about 1/6 cup (Hola Jalapeno) to 3/8 cup (Bayless) per cup of masa harina. Liquid starts around 3/4 cup (Maseca) and tops out at 1 1/3 cups (Hola Jalapeno, who keeps adding broth until the dough is almost soupy because it dries as it sits).
Salt goes from about 3/8 teaspoon (Maseca) to 3/4 teaspoon (Mama Maggie’s Kitchen’s 12-tamale batch), and baking powder from about 1/3 teaspoon (Isabel Eats) to 1 teaspoon (Hola Jalapeno).
Baking powder varies nearly threefold and fat more than twofold. Treat any ratio as a starting point and let the texture decide.
Fresh masa goes by weight instead. Muy Bueno, Rick Bayless and Everyday Southwest land at 2.5 to 3.3 pounds of masa per pound of lard, with only 1/5 to 3/4 cup of broth per pound of masa.
For liquid, use chicken, pork, beef or vegetable broth, or the cooking liquid from the filling meat (Mama Maggie’s Kitchen, Hola Jalapeno). Isabel Eats prefers low-sodium broth, and Mama Maggie’s Kitchen says to taste before salting because broth can already carry salt.
Temperature is another thing nobody agrees on. Bayless and Hola Jalapeno use hot or boiling liquid to rehydrate masa harina. Maseca and Mama Maggie’s Kitchen call for warm water or broth.
Cooler works too, since Pina en la Cocina uses cooled broth and the Isabel Eats team says broth doesn’t need to be warm.
Test old baking powder before it goes in the bowl. A splash of boiling water on a small amount should foam if it is still active (Muy Bueno).
Scaling a batch to 12, 50 or 100 tamales
Mama Maggie’s Kitchen scales one base recipe from 12 tamales up to 50 and 100 at nearly the same proportions.
| Tamales | Masa harina | Fat | Broth or water |
|---|---|---|---|
| 12 | 2 cups | 2/3 cup | 1 3/4 cups |
| 50 | 8 cups | 2 1/2 cups | 7 cups |
| 100 | 16 cups | 5 cups | 14 cups |
Tamale size decides the count. Maseca’s Tamal directions use about 2 ounces of masa per tamale and give no fixed yield per bag, while Isabel Eats gets about 100 tamales from a 4.4 pound bag.
Masa per tamale runs from 2 tablespoons (Muy Bueno) to 1/4 cup (Rick Bayless). Plan the batch around the husks you have, not around a fixed yield.
Step-by-step method for mixing masa for tamales
The fat goes in the bowl first and gets whipped. Masa and broth follow in turns, and you stop once the dough is as thick as hummus.
That order works for lard, shortening and masa preparada. Oil and rehydrated masa harina change it a little.
- Start with fat at room temperature, soft but not runny (Rick Bayless).
- Whip the fat with the salt and baking powder for 1 to 2 minutes, until light and airy.
- Add the masa in small batches or handfuls, alternating with the warm broth.
- Scrape down the bowl and keep mixing until the dough looks like thick hummus or smooth peanut butter (Isabel Eats, Muy Bueno).
- Add broth a splash at a time if it is stiff, or more masa harina if it is loose.
- Run the float test and correct the dough if it sinks.
- Cover the bowl and hold the masa at room temperature until the filling is ready (Muy Bueno).
Cooks disagree on resting. Muy Bueno skips it. Kevin Is Cooking rests masa for 30 to 60 minutes before spreading, and Rick Bayless refrigerates the batter for an hour and rebeats it for the lightest texture.
A rest also buys time to soak the corn husks if they are still dry.
Masa harina gets rehydrated first. Bayless stirs 3 1/2 cups into 2 1/4 cups of hot water, and Hola Jalapeno pours boiling broth over the flour and rests it 20 minutes before whipping it into the fat.
The oil version from Isabel Eats runs differently. She mixes the dry ingredients, works the oil in by hand until the dough feels like wet sand, then adds broth and mixes 3 to 5 minutes.
Packed fresh masa needs fluffing before use (Everyday Southwest), and Muy Bueno splits a 5 pound batch in two so the mixer isn’t overloaded.
Hand mixing works, but an electric mixer gives fluffier, lighter tamales (Hola Jalapeno). Hola Jalapeno lists a 5 quart KitchenAid as the minimum for 6 cups of masa harina.
Once the masa passes the float test, spread it on the husks and steam the tamales until the husk peels away cleanly (Rick Bayless).
Does masa for tamales have to float?
No, but it is the standard check. A floating dollop means air is trapped in the dough, and most sources treat a sinker as a cue to keep working, not as a failed batch.
Mexican Made Meatless (2022, updated 2026) calls the float test a helpful sign, not a strict requirement. Mama Maggie’s Kitchen says it isn’t the only way to judge masa, and that a soft, light, spreadable dough matters most.
How to run the test
The float test comes after mixing and before spreading. It takes seconds.
Drop in 1/2 teaspoon of masa (Rick Bayless, Muy Bueno) or up to a full teaspoon (Kevin Is Cooking, Mexican Made Meatless). The water is cold in the Bayless and Kevin Is Cooking recipes, and warm at Mexican Made Meatless, which argues warm water mimics the heat of steaming. Muy Bueno’s recipe card says warm while its tip box says cold.
A ready dollop floats back to the top within a second or two.
Recipes using either temperature treat a float as ready. Pick one and keep it the same between tests so the results compare.
What a float result does and does not tell you
Lucia Gomez, sous chef at Mezcal at Montage Los Cabos, describes masa as an emulsion of fat, so a sinker points to too little fat (Mashed, 2024). Ellen Marie Bennett, founder of Hedley & Bennett, says sinking masa needs more air and fat.
A float shows that air has been whipped into the dough (Mexican Made Meatless) and that there is enough fat in the emulsion (Mashed).
It says nothing about hydration, since sticky masa is a separate problem with its own fixes (Mexican Made Meatless). It says nothing about seasoning either. Mashed’s chefs say to taste the masa as you go, and a floater can still be bland.
Sources disagree on what a sinker costs you. Gomez says unfixed masa steams up dry and sticks to the husk, while Mexican Made Meatless says the tamales come out denser and suggests a thinner spread.
One reader comment on Mexican Made Meatless describes 90 minutes of mixing, with new lard and then shortening, and no float at all. The author’s reply was that the masa won’t ruin the tamales if it is well hydrated.
Treat the float test as a check on air, and judge hydration separately. A spoon drawn across the top should move the way frosting does (Mexican Made Meatless).
Fixing masa that is dry, wet, grainy or won’t float
Dry or grainy masa wants liquid, and wet masa wants more masa harina. Masa that sinks usually needs more whipping, and fat comes last.
| Symptom | Likely cause | First fix |
|---|---|---|
| Dry, stiff or cracking | Too little liquid | Add broth a splash at a time |
| Grainy | Too little liquid or fat, or no rest | Add both, then let the dough sit |
| Sticky or loose | Too much liquid | Mix in masa harina a tablespoon at a time |
| Sinks in water | Too little air, stale baking powder or low fat | Test the baking powder, then whip longer |
Mama Maggie’s Kitchen adds liquid and fat to grainy masa and liquid alone to stiff masa. Kevin Is Cooking rests the dough so the liquid soaks in and fully hydrates it.
Dry masa often goes unnoticed until the tamales come out of the steamer, so use all the liquid the recipe calls for (Mashed, 2024).
Sticky is where sources split. Muy Bueno says masa should be a bit sticky, like smooth peanut butter, and Mashed notes that well-hydrated masa can be sticky without being too wet. Mexican Made Meatless treats sticky masa as a sign of excess liquid.
Rick Bayless gives a physical test instead. The batter should hold its shape on a spoon, like soft but not runny cake batter.
The order of fixes for masa that sinks is contested too.
Mexican Made Meatless says to check the baking powder first (1/4 teaspoon in a small cup of water should bubble at once), then whip longer at a higher speed, then whip in 1/8 cup of broth, and add 1/8 cup of fat last, since she finds extra fat makes tamales greasy.
Muy Bueno’s recipe card says to add a little more lard, beat another minute and test again, though its tip box says to beat for 5 minutes and retest. Hola Jalapeno (2023) sides with the recipe card: a spoonful more lard, another minute of beating, and try again.
The camps differ on whether fat is the cause or a last resort. If an earlier batch stuck to the husk, too little fat is the likelier culprit (Mashed), and if the dough only needs air, whipping solves it.
Can you overmix? Mama Maggie’s Kitchen says there is no need to fear it and to keep beating until the masa floats, while Bennett warns that mixing far too long can knock the air back out.
Bennett puts total mixing at about 5 minutes in a stand mixer, 8 to 10 minutes with an electric hand mixer and 15 to 20 minutes by hand (Mashed, 2024).
She also whips the fat for about 4 minutes in a stand mixer, longer than the 1 to 2 minutes in the Rick Bayless and Mama Maggie’s Kitchen recipes.
Making masa for tamales ahead of time: refrigerating, freezing and rewhipping
Masa keeps one to three days in the refrigerator and three to six months in the freezer, depending on the recipe. Thawed masa comes back dry and dense, so plan on a splash of broth and a quick rewhip.
In the refrigerator it lasts up to 3 days, tightly covered (Isabel Eats, Muy Bueno, Kevin Is Cooking). Hola Jalapeno (2023) prefers masa fresh from the mixer and allows a day ahead as a compromise, brought to room temperature before use.
The freezer window is about 3 to 6 months (Mexican Made Meatless, 2023, updated 2026), or up to 6 months (Muy Bueno, Kevin Is Cooking). Thaw it overnight in the refrigerator, then let it come to room temperature before spreading (Muy Bueno, Kevin Is Cooking).
That freezer window is about quality, not safety. USDA’s Food Safety and Inspection Service says food held constantly at freezer temperature stays safe indefinitely and only its quality suffers over long storage (Freezing and Food Safety fact sheet, 2013 archive).
Pack the masa flat. Mexican Made Meatless rolls it thin in a sealed freezer bag to save space, and uses small bags so later batches stay small.
Ice crystals leave thawed masa drier and denser, according to Mexican Made Meatless. Her fix is to beat in vegetable broth a little at a time with a hand mixer, add some masa harina, and mix until the dough is light and airy again.
Run the float test on the revived dough before spreading.
Fresh masa straight from the tortilleria keeps up to 3 days in its bag or an airtight container, and turns sour in smell and taste once it goes off (Mexican Made Meatless). Freeze it if it won’t be used in time.
Spread tamales freeze raw too, and the rules for storing finished tamales differ from those for dough.
Masa for Tamales FAQ
Is masa for tamales gluten-free?
Yes. Tamale dough is made from corn, so it stays gluten-free as long as your kitchen avoids cross-contamination (Muy Bueno).
Maseca’s Tamal flour also carries a gluten-free certification on its label.
How do you add red or green chile to tamale masa?
Swap part of the broth for chile sauce so the total liquid stays the same. Pina en la Cocina replaces 1/2 cup of broth with 1/2 cup of red or green sauce in a 3-cup masa harina batch.
Ground ancho or guajillo powder adds color without the extra liquid.
Which changes make masa work for sweet tamales?
Replace the broth with piloncillo syrup, as Muy Bueno does for dessert tamales. Ellen Marie Bennett suggests butter in place of lard for sweet versions (Mashed, 2024).
Many sweet recipes also add sugar to the dough.
Can you nixtamalize your own corn at home?
Yes, but it takes about 11 hours, including a 9-hour rest. Pina en la Cocina cooks 2.2 pounds of corn in 3 liters of water with 4 teaspoons of calcium hydroxide (cal), then grinds it in a blender.
She mixes masa harina into the ground corn to firm the dough.
Does a food processor work for mixing tamale masa?
It does. America’s Test Kitchen’s tamale recipe processes masa dough, corn, butter and lard with the baking powder and salt for about 1 minute, until the mixture is light, sticky and very smooth.
Run the float test afterward, as with any other batch.
What can you do with leftover masa?
Make champurrado, the thick Mexican chocolate drink that masa thickens (Mama Maggie’s Kitchen).
Or steam it in a husk with no filling for a plain masa tamal, which the Isabel Eats team recommends.
A Reliable First Batch of Masa for Tamales
For a first batch, masa harina sold for tamales and lard or shortening is the easiest combination to correct by texture. The 12-tamale quantity keeps any mistakes small.
Read the package directions, mix 2 cups of masa harina, adjust by texture and then float-test.
Two cups keeps errors cheap, and it equals about one-eighth of the 16 1/2 cups Isabel Eats (2019) counts in a 4.4 pound Maseca bag, so one bag covers roughly eight practice batches.
What you give up is flavor, since masa harina trades the deeper corn taste of fresh masa for availability and a printed starting ratio (Mexican Made Meatless, 2023).
Bag sizes vary, with retail listings showing both 4 pound and 4.4 pound (70.4 ounce) Maseca Tamal bags, so measure by cup, not by bag.
With the dough ready, wrapping the tamales comes next.
