Some friends sent me some morita chiles (dried chipotles, basically) from their travels in Texas and Mexico, so I looked up recipes and found this one courtesy of seriouseats.com. Very simple (3 ingredients + a bit of water!) and *way* delicious! If you can't find moritas, you can substitute chipotles. We served as a dip for chips, but the poster recommends it both as a marinade and a topping for beef -- got to try that next!
