Wipe down the Cascabel chiles with a damp paper towel
Tear open the chiles and remove the stems and seeds
Tear each chile into 2-3 pieces
Using a comal or skillet on medium-low heat, cook the Cascabels until they soften and start to change color, about 1-2 minutes. Use a spatula to press them into the skillet.
Place chiles in a bowl and cover with hot tap water. Submerge and let reconstitute for 10-20 minutes.
Meanwhile, husk and rinse 2 tomatillos (I usually remove the stem but this is optional)
Roast tomatillos in the oven at 400F for 10-15 minutes or until they start to turn army green in color
Add tomatillos, chiles, and 2 peeled garlic cloves to a blender
Add approximately 1/4 cup of the soaking liquid to the blender, along with a pinch of salt and 1/4 teaspoon of apple cider vinegar
Pulse blend and taste for seasoning
Serve immediately
Store in an airtight container in the fridge
