Can I make the chili sauce ahead of time?
Yes. Prepare the chili sauce by rehydrating the dried chiles and blending them with garlic and hot water up to 1 day ahead. Store in an airtight container in the refrigerator.
What dried chiles work best for the sauce?
Ancho, guajillo, or New Mexico chiles are traditional choices. Avoid overly spicy varieties like chipotles if you prefer milder heat.
How do I get the potatoes crispy?
Cube the potatoes into small, uniform pieces and cook them in the bacon fat over medium-high heat, stirring occasionally, until golden and tender at the edges—about 8-10 minutes.
Can I use a different cheese?
Yes. Cheddar, Monterey Jack, or a blend of Mexican cheeses work well. The key is choosing a cheese that melts smoothly.
Can this be meal-prepped?
Prepare the skillet filling up to 2 days ahead and refrigerate. Reheat gently in a skillet before serving with warm tortillas.
