Gourmet Huevos Rancheros - cooking recipe

Ingredients

4 (6 inch) corn tortillas
1 cup canned refried beans
2 tablespoons unsalted butter or 2 tablespoons vegetable oil
8 large eggs
salt and black pepper, freshly ground
1/2 cup monterey jack cheese, grated
1 avocado
2 teaspoons lime juice, fresh
1/2 cup prepared salsa
1/2 cup sour cream
1/4 cup fresh cilantro, coarsely chopped
1 green onion, white and green parts (thinly sliced on the bias)

Preparation

Preheat the broiler.
Heat the tortillas by toasting them one at a time in a dry cast-iron skillet or directly over a gas flame until lightly toasted; Place on a baking sheet, spread each tortilla with 1/4 cup of refried beans, and cover to keep warm.
Working in batches as needed, heat the butter in a large skillet over medium-high heat until it is very hot but not smoking and the foaming has subsided; Crack the eggs directly into the hot butter and reduce the heat to medium-low or low; Fry the eggs, shaking the pan occasionally to keep the eggs from sticking; Season the eggs with salt and pepper; Fry to the desired doneness, about 2 minutes for \"sunny-side up,\" 3 minutes for medium yolks, and 4 minutes for hard yolks; Or, once the whites are just opaque, turn the eggs and cook for 30 seconds more for \"over easy,\" 1 minute more for \"over medium,\" or 2 minutes more for \"over hard.\".
Top each tortilla with 2 fried eggs and 2 tablespoons of the grated cheese; Slide the tortillas under the broiler to melt the cheese.
Meanwhile, dice the avocado and toss with the lime juice to prevent the avocado from discoloring.
Top each serving with 2 tablespoons salsa and 2 tablespoons sour cream; Divide the avocado among the tortillas; Garnish each tortilla with 1 tablespoon cilantro and 1 tablespoon green onion and serve.
