Season beef with spices. Let marinate if possible. Put ground beef in a cold, large pot. Do not use oil. Ground beef makes it's own fat!

Drain oil. Deglaze pan with beef stock by scraping the fond off the bottom of the pot. When the brown bits are lifted off the bottom of the pot, return the beef to the pot.

Reduce liquid until fully absorbed. Add salsa. Reduce until liquid is absorbed and you reach your desired consistency.

Variations; Tequila, any different salsa you like, small diced bell peppers and hot peppers, shredded cheese, lime juice/zest, smoked paprika, cilantro, tomatillos, cinnamon (add before salsa)

Also try tamarind, fresh tomatoes, sherry, sherry vinegar, zucchini, potatoes
