Step 1

Bring 4 cups of water to a boil. Place the guajillo and ancho chiles in a heat-proof bowl. Pour the water over them until they're completely submerged. Let them soak for 10-15 minutes, until soft. Strain the chiles and reserve the liquid. Set them aside.

Step 2

Add the soaked chiles, chipotle in adobo, salt, and pepper to a blender. Pour in 1/2 cup of the chile's soaking liquid. Process everything until you get a smooth mixture. Season with more salt and pepper to taste. Strain the sauce and set it aside.

Step 3

Place a large pan over medium-high heat. Add the vegetable oil and let it heat for 1-2 minutes. Add the ground beef. Let it cook for 8-10 minutes, until browned. Use a spatula to break up the meat as it cooks.

Step 4

Sprinkle in the cumin, oregano, paprika, salt, and pepper. Mix to combine.

Step 5

Reduce the heat to medium-low and pour the blended sauce in. Mix well. Let it simmer for 15-20 minutes, but don't let the sauce be completely absorbed so keep an eye on the stove.

Step 6

Season with more salt and pepper, to taste. Remove from the heat and serve as desired.
