The ancient coupling of chiles and cocoa provides rich, complex flavor to braised mole beef. For a simple twist on this authentic Mexican dish, spoon beef into lightly crisped tortilla and top with traditional Mole garnishes.
Mix all Spice Blend ingredients in small bowl. Set aside
For the Mole Beef, heat 1 tablespoon of the oil in 5-quart Dutch oven or saucepot on medium-high heat. Add 1/2 of the beef; brown on all sides. Repeat with remaining beef. Remove beef. Set aside
Heat 1 tablespoon of the oil in same Dutch oven on medium heat. Add onion; cook and stir 3 minutes. Add water; stir to loosen browned bits in bottom of pan. Add beef, beef stock, tomato paste and Spice Blend; mix well. Bring to boil. Reduce heat to low; cover and simmer 30 minutes, stirring occasionally. Stir in chocolate. Simmer, uncovered, 1 hour or until beef is tender and sauce has thickened, stirring occasionally
Brush both sides of tortillas lightly with remaining 1 tablespoon oil. Cook each tortilla in nonstick skillet on medium heat 1 minute per side or until tortilla is slightly crisp but still pliable. Drain on paper towels. Spoon about 1/4 cup Mole Beef into center of each tortilla. Top with desired garnishes. Fold and serve
