3 to 5 lbs. beef, inexpensive cut such as brisket
1 c. vinegar
Garlic
Onion
2 c. strong black coffee

Cut deep slits in meat. Insert slivers of garlic and/or onion into slits. Pour 1 cup vinegar over meat, making sure it runs into slits. Put in refrigerator 24 to 48 hours. When ready to cook, place in big heavy pan (iron, if possible) and brown in oil until nearly burned on all sides.

Pour strong black coffee over meat. Add 2 cups water. Simmer covered on top of stove 4 to 6 hours. Season with salt and pepper 20 minutes before serving. NOTE: Even the toughest cut of beef will become very tender. The acid in vinegar tenderizes meat.
