A really lovely cousin to the Anasazi bean, Vaquero have intriguing black and white markings, not unlike an appaloosa horse might don. The flavor is somewhat like the Anasazi but it's a little lighter. The real fun is the inky, black pot liquor. It looks cool and tastes great.
In a large pot, sauté aromatic vegetables (onions, garlic, celery, carrot, etc.) in olive oil. Add beans and enough water to cover by about 2 inches. Bring to a full boil for 10 to 15 minutes. Reduce heat to a gentle simmer, using a lid to help regulate the heat, and gently cook until done, 1 to 3 hours. Salt when the beans start to soften. A pre-soak of 2 to 6 hours will lessen the cooking time.
