Put all ingredients in a blender or food processor and blend until smooth, about 30 seconds.
If you don’t have a blender or food processor, you can make it by hand, but it won’t be quite as smooth. Mince the chipotle peppers really small, until it makes a paste. Then stir everything together in a large bowl until combined.
Chipotles are quite spicy. If you're not sure about the spice level, I would start with just 1 or 2 chiles and a couple small spoonfuls of the adobo sauce. Then, taste the sauce, and add more if you'd like the sauce to be spicier. You can also adjust the heat level by using more or less cayenne and hot sauce.
