Maseca Instant Corn Masa Flour is the world's leading brand of masa harina, made from nixtamalized white corn — a traditional process in which dried corn kernels are cooked and soaked in lime water (calcium hydroxide), then ground and dried into a fine flour. This Costco bulk case includes 10 individual 4 lb bags, totaling 40 lbs, making it ideal for restaurants, catering operations, tamale shops, and large households.

Maseca masa harina rehydrates instantly with water to form a smooth, pliable corn dough used across countless Latin American dishes. It is the essential ingredient for homemade corn tortillas, tamales, sopes, pupusas, gorditas, enchiladas, empanadas, and arepas. Its finely milled texture and consistent hydration make it the professional choice for high-volume production.
