Crispy Potato, Chorizo, and Green Chili Hash With Avocado and Eggs

"[Photographs: J. Kenji Lopez-Alt] Ultra-crisp potatoes fried in chorizo fat with chunks of chorizo, seared green chilies, and scallions, all topped with baked eggs, avocado, and cilantro. It's a heck of a way to start the day. Why this recipe works: * Par-boiling the potatoes gelatinizes starches so that they can crisp up better when the potatoes are subsequently fried. * Adding vinegar to the par-cooking liquid means that pectin, the organic glue that holds together vegetable cells, will not be destroyed as efficiently. This allows the potatoes to soften and cook without falling apart. * Frying the potatoes in chorizo fat builds their flavor. * Cooking all ingredients—potatoes, chorizo, and vegetables&mdash separately lets us ensure that each is perfectly cooked. * Straining the eggs through a fine-mesh strainer helps them keep a more natural shape during baking. * Post-bake toppings add freshness to a hearty meal. Notes: Russet potatoes will give you crisper end results, but the potatoes will fall apart a bit. Yukon golds will hold together and will have slightly creamier centers and less crispness than russets. About the author: J.
