This is scaled down and adapted from the original, as my pressure cooker is a smaller one, more like a deep pressure skillet. The cocoa and the chorizo make all the difference. A combination of ground meats works very well. Be sure to use whole cumin, as the ground stuff loses flavor when pressure cooked.
If you double it, use a four quart or larger cooker.
For a Cuban-style picadillo,reduce the chile powder to 1 tablespoon, add 2 to 3 tablespoons raisins, then add 1/4 cup coarsely-chopped pimento-stuffed green olives after pressure release. Garnish with cilantro and serve over rice.
