Frequently asked questions

Why are corn tortillas less processed?

Corn tortillas use nixtamalization, a 3,500-year-old process of soaking corn in lime water. The result needs only masa harina, water, and lime. Flour tortillas require added fat (for pliability), preservatives (for shelf life), and dough conditioners.
