Ways to celebrate

The tortilla in a quesadilla predates the Spanish arrival in Mexico by centuries — it's the cheese that's the newcomer.

Know what came before the cheese

Indigenous peoples in Mexico were already using tortillas as a dietary staple long before Spanish contact, filling them with native ingredients like pumpkin seeds, squash blossoms, and beans — but the cheese now central to a quesadilla wasn't part of that original recipe at all.

Trace the dish to colonial-era dairy

The defining change came in 1521, when Spanish settlers introduced cows, lambs, and sheep to New Spain — bringing dairy into Mexican cuisine for the first time and giving cooks the missing ingredient to combine with the tortilla they already had.
