This recipe is originally from El Bodegon de Guillermo in Tijuana. Before the restaurant burned in 1978, it was THE place to go. These quesadillas were reportedly loved by Sammy Davis, Jr.. If sqash blossoms are out of season, use canned squash blossoms—which is what La Fonda Robertos in Tijuana does. VARIATIONS: For Quesadillas de Chiles (Chile Quesadillas): Make a filling by mixing together 3 chopped, seeded, peeled poblano chiles (see step 1), 1 lb. grated monterey jack cheese, and salt and freshly ground black pepper to taste in a bowl, then proceed with steps 3-5. For Quesadillas de Papas y Chiles (Potato and Chile Quesadillas), follow method for chile quesadillas above, adding 1 large diced, peeled, boiled russet potato to filling before proceeding to steps 3-5. Prep time does not include the time to make fresh tortillas, if you choose this option.
