Peel and wash the tomatillos. Add them to a pot filled with 5 cups of water. Bring up to a light boil at medium heat. Cook them just until they turn from bright green to olive green most of the way. Cover them and set them aside.
Remove the stems and seeds from the chile ancho and guajillo. Remove just the stems from the chile de arbol. Set aside.
In a medium skillet, pour in 2 tablespoons of oil and heat to medium. Add the garlic, chile piquin and chile de arbol. After a few minutes it should begin to sizzle and become aromatic. Stirring often, continue cooking until garlic lightly browns and chiles darken in some spots. Transfer to the blender jar.
In that same skillet at medium heat, lightly fry and toast the chile ancho and guajillos for 1-2 minutes, turning often. Transfer to the blender jar.
To the blender, pour in 2 cups of the cooking water from the tomatillos. Season with 1 teaspoon of salt. Blend on high until very smooth. Using a slotted spoon, add the cooked tomatillos to the blender jar. Cover and again, blend on high until smooth. The salsa should be very smooth looking. If it's too thick, pour in more water. It should flow easily. If needed, blend for another minute. Set aside.
In a large skillet, preheat 2 tablespoons of oil or pork lard at medium heat for a few minutes. Once it's hot, pour in the salsa from the blender. Rinse out the blender jar with 1 cup of water, then pour that into the skillet. Stir well to combine. Reduce heat slightly. In a small bowl mix the instant coffee with 2 tablespoons of hot water. Pour into the simmering salsa. Stir well to combine. Taste for salt. Continue cooking for 10 minutes.
