Heirloom, Blue or Maseca? The Best Masa Harina for Tortillas

Every corn tortilla starts with masa, a dough of corn that has been cooked with lime and ground. Few home kitchens in the United States have a tortillería around the corner selling it fresh, so most home cooks make tortillas from masa harina: the same masa, dried and ground into flour. Add warm water, and twenty minutes later you can be pressing tortillas.

The bags on the shelf are not all alike, though. Some are a single heirloom corn from one region of Mexico; others are blended commercial flours with added vitamins, and a few carry gums and oil that make them closer to a tortilla mix. White, yellow and blue corn each taste different. This guide explains what to look for, names the masa harinas worth buying, and shows how to turn a bag into a stack of soft tortillas.

Masa harina, cornmeal and masa preparada: not the same thing

Three corn products sit side by side on many shelves, and only one makes tortillas.

• Masa harina is masa that has been dried and ground again into flour, as America’s Test Kitchen defines it. The corn has already been cooked and soaked in limewater, which is why it forms a dough with nothing but water.
• Cornmeal and corn flour are ground from uncooked dried corn that has not been treated with lime. They will not hold together as a tortilla dough, however much water you add.
• Masarepa, sold by brands such as P.A.N. and Goya for arepas, is precooked corn flour that has not been nixtamalized, according to America’s Test Kitchen. It is not a substitute for masa harina.
• Masa preparada is fresh masa that a tortillería or Mexican market has already mixed for tamales, usually with fat and salt. It is perishable and meant for tamales, not tortillas.

The process that makes masa harina different is nixtamalization: dried corn is cooked in an alkaline solution of water and lime (calcium hydroxide, not citrus), steeped, washed and ground. Our guide to nixtamalization explains it step by step, including why it changed the nutrition of corn and how it has been done for about three thousand years. If a bag says “masa harina”, “instant corn masa flour” or “harina de maíz nixtamalizado”, it is the right product. If it says “cornmeal”, “corn flour” or “pre-cooked”, it is not.

Our picks for the best masa harina for tortillas

These seven bags cover the masa harinas a home cook in the United States can buy online today: two heirloom flours, one from Bob’s Red Mill, two familiar Maseca flours in blue and yellow, a bulk pack from Minsa and an organic flour certified gluten-free. Each pick explains what is in the bag, what it suits, and one honest reason to skip it.

How to choose a masa harina for tortillas

Five things decide which bag suits you. The color on the front matters less than what is listed on the back.

1. Check that it is nixtamalized

Look for “masa harina”, “instant corn masa flour” or “nixtamalizado”, and for lime (or calcium hydroxide) in the ingredients. Cornmeal, corn flour and pre-cooked arepa flour will not make tortillas.

2. White, yellow or blue corn

Masienda’s view is that any color works for any masa recipe, with subtle differences in flavor and texture. White corn makes the softest, most delicate tortillas, the everyday table tortilla in much of central Mexico. Yellow corn tastes more strongly of corn and makes a sturdier tortilla that holds up to frying, which is why many cooks use it for tostadas and chilaquiles. Blue corn is the most distinctive: nuttier, earthier and darker. Start with white if you are unsure.

3. Heirloom or commercial

Heirloom masa harina, such as Masienda’s, is made from a named, open-pollinated corn variety grown by small farmers, and it tastes of that corn. Commercial flours such as Maseca and Minsa are blended for consistency, ground very fine and easy to work, and cost less. Heirloom flours usually need a little more water and a little more patience; commercial flours forgive more.

4. What else is in the bag

The simplest masa harina is corn and lime. Some commercial flours add folic acid, which the FDA allows, and some add more: one reseller’s copy of a Minsa bag lists oil, salt and gums, which help the dough hold together but change the taste and texture. Neither is wrong, but read the ingredients so you know whether to add salt yourself.

5. Organic, non-GMO and gluten-free claims

If these matter to you, buy a bag that states them. Bob’s Red Mill and Chef Mex are certified organic; Masienda states non-GMO; Chef Mex is the one bag here sold as certified gluten-free. Corn itself contains no gluten, but only the maker can tell you about cross-contact in the mill.

From bag to tortilla: mixing masa harina

The method is the same for every bag; only the amount of water changes.

1. Weigh the masa harina. Two cups is a good first batch for a family. A kitchen scale makes the next batch easier to repeat.
2. Add warm water a little at a time. Masienda recommends water at about 100°F. Its staff suggest roughly 150 grams of its masa harina to 257 grams of water; commercial flours often need less. Mix with your hand until there are no dry spots.
3. Knead until it feels like soft clay. The dough should be moist, smooth and not sticky. Cover it with a damp cloth and let it rest for 15 to 20 minutes so the flour finishes absorbing the water.
4. Test one tortilla. Rick Bayless’s rule is to look at the edges of the first pressed tortilla: if they are rough and cracked, the dough needs more water. Work in a spoonful and press again.
5. Press and cook. Masienda suggests balls of about 32 grams for a standard tortilla. Press between two plastic liners, then cook on a hot, dry comal for 20 to 30 seconds a side, turning once more so it puffs.
6. Stack and cover. Move each tortilla straight into a cloth or warmer so the stack stays soft.

The tools for every step are in our guide to tortilla making tools. A cast iron or carbon steel pan does the cooking best; see the best comal for tortillas. If you would rather not press and flip by hand, an electric tortilla maker is another route, though most are designed for flour tortillas.

How we picked these seven masa harinas

We started from what a Mexican kitchen asks of masa harina: properly nixtamalized corn, good corn flavor, a dough that presses cleanly and puffs on the comal, and an ingredient list you can trust. We then narrowed the field to bags sold on Amazon in the United States and in stock when we checked, from makers we could identify, and confirmed each one’s ingredients and claims from the maker or the brand’s Amazon listing. Where the listing was thin, we used grocery retailers’ published ingredient panels and say so; where we could not confirm a detail, the review says “Not stated” or “check the bag”. For definitions we relied on America’s Test Kitchen, for folic acid on the US Food and Drug Administration, and for mixing on Masienda’s and Rick Bayless’s published instructions. Several good flours are missing because they were out of stock or nearly so on Amazon when we checked, including Masienda’s white, blue and organic flours and its Masa Taquera, and Maseca’s classic white flour. We left out a listing that copied another maker’s product text, and arepa flours, which are not nixtamalized. We have not cooked with every flour listed here; where we describe how a flour behaves, we say whose description that is.

Masa harina questions, answered

What is the best masa harina for corn tortillas?

For flavor, an heirloom flour made only from corn and lime, such as Masienda’s yellow masa harina. For an easy, consistent everyday flour, Bob’s Red Mill or Maseca. Our guide to corn versus flour tortillas explains why corn tortillas need masa rather than wheat flour.

Can I use cornmeal instead of masa harina?

No. Cornmeal is ground from corn that has not been nixtamalized, so it will not form a dough that holds together when pressed. Pre-cooked arepa flour is not a substitute either.

Is masa harina gluten-free?

Corn contains no gluten, and many masa harinas are sold as gluten-free, including Masienda’s and Maseca’s. If you must avoid gluten, buy a bag the maker states is gluten-free or certified, such as Chef Mex, because mills can handle wheat too.

How much water do I add to masa harina?

Follow the bag, then adjust by feel. Commercial flours usually take a little more than their weight in water; heirloom flours often take more. Masienda’s staff suggest about 150 grams of its masa harina to 257 grams of warm water. The dough is right when it feels like soft clay and the edges of a pressed tortilla do not crack.

Can I make tamales with the same masa harina?

Yes. Every flour here suits tamales as well as tortillas. For tamales, the masa is beaten with fat and broth until light, and coarser “tamal” flours from the same brands are also sold for that purpose.

How long does masa harina keep?

Bob’s Red Mill gives its golden masa harina a 24-month shelf life, and Masienda and La Mazorca de Oro say to store their masa harina in a cool, dry place. Once opened, keep the bag tightly sealed; if it smells stale or musty, replace it.

The bag we would reach for

Buy Bob’s Red Mill Organic for an easy-to-find, two-ingredient organic flour. Choose Masienda’s heirloom yellow masa harina if you want tortillas that taste of corn, from nothing but corn and lime, Maseca blue or yellow for color and frying, Minsa in bulk if you cook for a crowd, and Chef Mex if you need a certified gluten-free bag. Whichever you choose, add the water slowly, rest the dough, and let the first tortilla tell you if it needs more.

Masa harina is where a tortilla starts; our guide to tortilla making tools covers the press, the comal and the warmer that finish the job, and the best tortilla warmer keeps the stack soft at the table.
