This recipe will make an inexpensive cut of meat as tender as a more expensive cut.

1 (4 to 8 pound) roast beef
1 onion, chopped
1 cup vinegar
1 cup strong coffee
1 cup water
Garlic

Make incisions clear through meat. Open up with finger and stuff each slit with onion and 1 clove garlic. Make as many incisions as the meat will take. Pour vinegar over the top of the roast. Cover and refrigerate overnight.

Preheat oven to 325 degrees F.

Put meat and liquid into a cast iron skillet, and sear until almost burnt. Add coffee and water. Cover and place in oven and bake until very tender. More water may be added if necessary.
