1/2 c. tomato sauce
1 c. strong black coffee
1/4 c. Worcestershire sauce
1 tbsp. sugar
1 tbsp. salt
1/2 c. butter

Combine all the ingredients in a saucepan and simmer just until butter is melted. Use as a marinade for any meat. (It's especially good for flank steak) or brush on meat as a BBQ sauce.
