In a large bowl, combine the seeded dried chiles and 3 cups of hot water. Let the chiles soak for about 20 minutes, until softened. Using a slotted spoon, transfer the softened chiles into a large blender. Add in 1 cup of the chile-soaked water, the remaining 1 cup of fresh water, minced garlic, salt and the Abuelita Mexican chocolate. Blend until smooth. Cover and store in an airtight container in the refrigerator until ready to use, up to two weeks.
