In this easy, homemade barbecue sauce, beer balances the sweetness of molasses while hot sauce provides heat. Brush on grilled chicken, tofu or shrimp during the last 5 to 10 minutes on the grill or use as a dipping sauce.
Combine all ingredients except the hot sauce in a heavy medium saucepan; bring to a simmer over medium-high heat, stirring. Reduce heat to maintain a simmer and cook, stirring frequently, until reduced to about 1 1/2 cups, 20 to 25 minutes. Stir in hot sauce.
