Quesadillas de Flor de CalabazasGolden squash blossoms are used extensively throughout Mexico as a filling for quesadillas. These beautiful blossoms are becoming more available in the United States in season at farmers' markets and in some Mexican or Italian markets. The cooked filling of chopped blossoms, onion, garlic, tomato, and epazote is tucked inside a folded tortilla and lightly fried. This version from food stalls in Puebla's public market uses ready-made corn tortillas for convenience. Most authentic quesadillas are made with uncooked masa dough that is pressed into tortillas, filled, folded, and then fried.
