Many Mexican recipes start with a paste made with various rehydrated dried chiles, onion and fruit juices. Here a paste is used as a spicy marinade to flavor tender chunks of lamb. The hearty taste of red meat and the spicy heat of chiles creat the perfect marriage. For a smoky heat, try chipotle chiles. For over-the-top heat, use scotch bonnet chiles. For a nice bit of spice without a lot of burn, experiement with jalapeno or serrano chiles. Serve the lamb rolled in warm tortillas accompanied by the traditional beans and rice. Try the paste on chicken, beef or pork, too. Time does not include marinating time.
