Pure and simply, Tostada means “toasted”. The basis for the tostada is the tortilla. To most of us in much of the United States, tortilla means the flour version which is the wrapper for Burritos and the base for Quesadillas. The taco, from which most tostadas are made, uses corn tortillas. These are among the most ancient of all foods in the Western Hemisphere. For more than 7000 years, the natives grew the precursor to corn. It wasn’t until 3000BC that people in the Sierra Madre mountains hybridized what was to become the large, nutritious kernels we call corn. Its introduction was one of those amazing cultural moments of discovery. A Mexican anthropologist, Arturo Warman, went so far as to credit the development of both Maya and Aztec civilizations to the development of corn. Indigenous peoples viewed corn as “the foundation of humanity….the seed of life” and according to their legend, human beings were made of corn by the Gods. When the Spaniards arrived in the 1400s, what is now Mexico had a sophisticated cuisine made up of native fruits, game, beans, corn and turkeys.
The earliest Tostadas were dry-toasted in a pan without any oil. Now, it is far more common for tostadas to fried in a small quantity of oil. There’s also a deep frying option which can be achieved in about 30 seconds a side. And you can even spray the corn tortilla with oil, then bake it in a very hot oven for about three minutes. Ours were fried in oil as you can see. Here is the recipe.
Recipe for Steak Tostadas with Cashew Salsa and Red Cabbage Slaw
Active Time: 1 hour. Total Time: 1 hour. 4 Servings
For the Salsa:
2 Fresno or other red chiles
2 garlic cloves, unpeeled
½ cup cashews
2 tablespoons apple cider vinegar
¼ teaspoon sugar
Kosher salt
Slaw and Assembly
2 tablespoons apple cider vinegar
2 tablespoons mayonnaise
2 tablespoons plain Greek yogurt
¼ large head of red cabbage, very thinly sliced (about 4 cups)
1 scallion, chopped
Kosher salt
1 skirt, hanger or NY Strip steak (about 1½ pounds),
Freshly ground black pepper
1 teaspoon ground cumin
1 tablespoon vegetable oil; plus more for frying (about ⅓cup; optional)
8 small corn tortillas
Chopped cilantro and lime wedges (for serving)
For the Salsa:
1. Preheat oven to 350°. Roast chiles and garlic on a rimmed baking sheet until lightly browned and softened, 12–15 minutes. Add cashews to baking sheet and roast until nuts are golden brown, 5–7 minutes. Let cool slightly, then peel garlic. Transfer garlic, cashews, and chiles (include all the seeds if you like things hot, or half of them if you aren’t sure) to a blender;
2. Add vinegar, sugar, and ½ cup water and purée until smooth. Season with salt.
Do Ahead: Salsa can be made 1 week ahead. Cover and chill.
For the Slaw and Assembly:
1. Whisk vinegar, mayonnaise, and yogurt in a medium bowl. Add cabbage and scallion and toss to coat; season with salt. Set aside.
2. Season steak with salt and pepper; sprinkle with cumin. Heat 1 Tbsp. oil in a large skillet over medium-high. Cook steak until deeply browned, about 4 minutes per side for medium-rare. Transfer to a cutting board; let sit 10 minutes before slicing.
3. Meanwhile, if making your own tostadas, pour oil into a small skillet to ¼” depth. Heat over medium. Working one at a time, fry tortillas until crisp, about 1 minute per side. Transfer to paper towels.
4. Top tostadas with some salsa, followed by steak, more salsa, slaw, and cilantro. Serve with lime wedges.
