How to Make Corn Tortillas from Scratch (With Real Corn)

There's nothing quite like a fresh, handmade corn tortilla, warm, pliable, with that unmistakable aroma of real corn. If you've only ever had store-bought tortillas, you're in for a revelation. Making corn tortillas from scratch using real nixtamalized corn is easier than you think, and the flavor difference is night and day.

This guide walks you through the full process, from nixtamalizing whole dried corn to pressing and cooking perfect tortillas every time.

Why Make Tortillas from Real Corn?

Most "homemade" tortilla recipes start with masa harina (instant corn flour). That works, but it's like comparing instant coffee to fresh-brewed. When you start with whole dried corn and nixtamalize it yourself, you get:

• Richer flavor: real masa has a complex, earthy sweetness that instant flour can't match
• Better texture: fresh masa produces softer, more pliable tortillas
• More nutrition: nixtamalization releases niacin (vitamin B3) and increases calcium content
• No preservatives: just corn, water, and cal (food-grade lime)

What You'll Need

Ingredients

• 2 lbs dried corn for tortillas (white, yellow, or blue corn)
• 1 tablespoon food-grade cal (calcium hydroxide)
• Water
• Pinch of salt (optional)

Equipment

• Large pot (at least 6 quarts)
• Corn grinder or food processor
• Tortilla press or heavy flat surface
• Cast iron skillet, flat griddle, or comal
• Parchment paper or plastic wrap

Step 1: Nixtamalize the Corn

Rinse the corn thoroughly to remove any debris before cooking

This step takes about 30 minutes of active time and 8-12 hours of soaking. Plan to start the night before.

1. Rinse the dried corn and remove any debris or damaged kernels
2. Dissolve 1 tablespoon of cal in 8 cups of water in your large pot
3. Add the corn and bring to a boil, then reduce to a simmer
4. Cook for 30-45 minutes. The corn should be soft but not mushy. The skin should peel off easily when rubbed between your fingers
5. Remove from heat and let the corn steep in the liquid (nejayote) for 8-12 hours or overnight
6. Drain and rinse the corn thoroughly, rubbing the kernels to remove the outer hulls (pericarp). This is now nixtamal

Step 2: Grind into Masa

1. Grind the nixtamal using a corn grinder (molino), food processor, or metate. Add small amounts of water as needed
2. Test the texture, the masa should be smooth, moist, and hold together when pressed. If it cracks at the edges, add a little more water
3. The consistency should feel like soft play dough, not sticky, not dry

Step 3: Press the Tortillas

Carefully peel the pressed tortilla off the parchment paper

1. Form golf ball-sized portions of masa (about 35-40 grams each)
2. Line your tortilla press with plastic wrap or parchment on both sides
3. Press firmly but don't smash. You want even thickness, about 2mm
4. Carefully peel the tortilla off the plastic

No press? Use a heavy skillet, cutting board, or even a glass baking dish to press between two sheets of plastic.

Step 4: Cook the Tortillas

Cook on a dry skillet until you see brown spots and the tortilla puffs

1. Heat your comal or skillet over medium-high heat (no oil needed)
2. Place the tortilla on the hot surface. Cook for about 60 seconds until the bottom has light brown spots
3. Flip once and cook another 60 seconds
4. Flip again briefly. If your heat is right, the tortilla should puff up (the sign of a perfect tortilla!)
5. Transfer to a towel-lined basket and keep covered to stay warm and pliable

Tips for Perfect Tortillas

• Corn variety matters: Blue corn makes sweeter, nuttier tortillas. White corn is the classic choice. Yellow corn works great for chips
• Don't skip the soak. The 8-12 hour steep is what makes nixtamalization work. Shortcuts here mean tough tortillas
• Moisture is key. If your masa is too dry, tortillas crack. Too wet, they stick. Adjust gradually
• High heat. A properly heated comal is essential. If tortillas don't puff, increase the heat slightly
• Eat fresh. Homemade corn tortillas are best within a few hours. Reheat on a dry skillet, never microwave

Yield

2 lbs of dried corn makes approximately 3 lbs of masa, which yields about 30-35 tortillas (5-inch diameter).

Ready to Start?

The hardest part of making corn tortillas from scratch is just starting. Once you've done it once, you'll never want store-bought again.
