Coffee is an excellent addition to many marinades and sauces. The coffee flavor balances and smoothes ingredients such as tomato sauce, mustard and vinegar. This sauce is excellent for grilled meats.
In a large non-reactive saucepan, combine the cooled coffee, tomato paste, water, mustard, horseradish, brown sugar, Worcestershire sauce, butter, pepper, garlic powder, salt and cayenne pepper.
Bring the sauce to a quick boil over high heat.
Stir and blend well. Reduce the heat and simmer over very low heat, uncovered, for 10 to 15 minutes.
Can use as a marinade or as a sauce to top steaks, pork chops, chicken or ribs hot off the grill. Use immediately or refrigerate for up to 3 weeks in an airtight container.
