Are corn tortillas gluten-free? Usually, check for wheat in the mix

Usually yes. A corn tortilla is masa: corn cooked with lime, ground, and mixed with water. None of that contains gluten.

What to check

• Blends: some supermarket “corn” tortillas add wheat flour for softness. Read the ingredients, or look for a gluten-free label.
• Restaurants and taquerias: corn and flour tortillas are often warmed on the same griddle or in the same steamer. Ask for yours on a clean surface.
• Hard taco shells and tostadas are usually corn too, but some are fried in oil shared with breaded food.
