It seems like every rib recipe out there has a "secret" ingredient, whether that's a cinnamon-spiced dry rub, a citrusy wet rub, or a tequila-spiked BBQ sauce. However, one ingredient commonly featured in rib recipes brings both flavor and improved texture to the party.
Coffee is an excellent marinade addition because it is acidic — a quality central to tenderizing meat. It's a favorable option because unlike common marinade ingredients such as vinegar or lemon juice, it contains just enough acidity to help the tenderizing process, yet preserve the meat's texture.
The cooking blog, Cleo Coyle Recipes, suggests a one-hour bath in cold coffee for baby back or spareribs. Afterward, you should season the ribs, basting them with BBQ sauce, and bake them in a hot oven for about an hour and a half.
