Store-bought tortillas are mostly cardboard. Honestly, they are. If you’ve been eating those stiff, crumbly rounds that break the second you fold a carnitas taco, I’m sorry. You deserve better. The difference between a bag of pre-packaged "corn discs" and a warm, puffed-up tortilla you just pulled off a hot cast iron skillet is the difference between a grainy black-and-white photo and 4K resolution.
Learning how do i make corn tortillas isn’t just about the recipe. It’s about understanding the chemistry of masa. You only need two ingredients—maybe three if you count salt—but the technique is where people usually mess up. Most home cooks quit because their dough is too dry or their tortillas won't puff. But once you get the rhythm down, you’ll never go back to the plastic bags in the bread aisle.
The Secret Ingredient You Can't Skip
You can't just grind up popcorn and call it a day. The heart of every real tortilla is nixtamalized corn. This is an ancient process where dried corn is soaked and cooked in an alkaline solution, usually limewater (calcium hydroxide). This isn't just for flavor. It unlocks niacin (Vitamin B3), which prevents diseases like pellagra, and it changes the structure of the corn so it actually forms a dough. Without nixtamalization, corn flour just turns into gritty mush.
For most of us, that means buying Masa Harina.
Don’t confuse this with cornmeal or corn flour. If you try to make tortillas with cornmeal, you’re going to have a bad time. Brands like Maseca are the gold standard in most grocery stores, but if you can find Masienda or Bob’s Red Mill, the flavor profile shifts from "fine" to "earthy and incredible." Masienda, specifically, works with small-holder farmers in Mexico to source heirloom landrace corn. It tastes like actual corn, not just yellow dust.
Getting the Hydration Right (The Part Everyone Misses)
Most bags of masa harina give you a 1:1 or 2:1 ratio. Ignore them. Sorta.

The weather in your kitchen matters. If you're in a humid basement in Seattle, you'll need less water than if you're in a dry kitchen in Phoenix. You want the dough to feel like Play-Doh. It should be supple. If you squeeze a ball of it and the edges crack, it's too dry. Add water a tablespoon at a time. If it sticks to your hands like glue, it’s too wet. Add a pinch more masa.
The Resting Phase
Once you’ve mixed your masa and warm water—warm water helps the starches hydrate faster—you have to let it sit. Cover it with a damp cloth. Let it rest for at least 15 to 20 minutes. This is non-negotiable. During this time, the dehydrated corn flour fully absorbs the moisture. If you skip this, your tortillas will feel "sandy" on the tongue.
The Equipment: Do You Really Need a Press?
Technically, no. You could use a heavy casserole dish or a skillet to smash the dough balls. But honestly? Buy a press. A heavy cast-iron press, like the ones from Victoria or Verve Culture, provides the even pressure you need for a thin, consistent tortilla.
Pro tip: Never put your dough directly on the metal. It’ll stick and you’ll be scrubbing for an hour. Use a plastic liner. A gallon-sized freezer bag cut into two squares is the secret weapon of every abuela I’ve ever met. It’s thicker than plastic wrap, so it doesn’t crinkle and leave weird lines on your tortilla.
The Heat: Why Your Tortillas Aren't Puffing
When people ask how do i make corn tortillas that puff up like a balloon, the answer is almost always temperature.

You need a comal or a flat cast-iron griddle. It needs to be hot. Not "warm," but medium-high heat. If your pan isn't hot enough, the tortilla will dry out before it cooks, turning into a cracker. If it’s too hot, the outside burns before the inside is done.
The "Puff" is a sign of success. It means the water inside the dough has turned to steam and trapped itself between the two cooked outer layers. It’s beautiful.
The Three-Flip Rule
- The First Sear: Lay the tortilla down. Wait about 30 to 45 seconds. The edges will start to lift slightly and the color will change. Flip it.
- The Cook: This side stays down longer—maybe 60 seconds. You want to see some light brown spots (the "leopard spotting"). Flip it again.
- The Puff: Within 15 seconds of the second flip, the tortilla should start to inflate. You can gently press the center with your spatula or finger to encourage the steam to spread.
Common Mistakes and How to Fix Them
Sometimes things go wrong. Even for experts.
If your tortillas are brittle, you didn't use enough water or you cooked them too long. If they are gummy, you didn't cook them long enough or the heat was too low.
Another big one: The thickness. If the tortilla is too thick, the edges will stay raw and doughy while the middle burns. If it's too thin, it'll shatter. Aim for about 1/16 of an inch. It takes practice. You'll probably mess up the first five. That’s okay. Feed the failures to the dog or chop them up and fry them for chilaquiles.

Storing Your Hard Work
As soon as a tortilla comes off the heat, it needs to go into a tortillero (a tortilla warmer) or a clean kitchen towel folded inside a bowl. This "steaming" period is crucial. It softens the outer crust and makes the tortillas pliable. If you leave them out on a plate, they’ll turn into cardboard in minutes.
Fresh corn tortillas are a revelation. They smell like toasted grain and summer. They have a sweetness that no preservative-laden grocery store version can mimic.
Actionable Steps for Your First Batch
Ready to start? Don't overthink it. Just do this:
- Buy the right flour: Look for Masa Harina, specifically "Nixtamalized." Avoid cornmeal.
- Use warm water: It makes the dough much easier to handle and prevents graininess.
- The "Squish" Test: Roll a small ball of dough and flatten it between your palms. If the edges crack, add a teaspoon of water to the whole batch.
- Prep your plastic: Cut a freezer bag into two squares for your press.
- Preheat that cast iron: Let your skillet get hot for 5 minutes before the first tortilla hits the surface.
- Stack and steam: Have a towel-lined container ready. The steam is what makes them soft enough to fold.
Keep the leftover masa in the fridge for up to two days, but honestly, you’re probably going to eat the whole batch in one sitting.
