T.G.I. Friday's Jack Daniels Sauce

Step 1
Preheat the oven to 325 degrees F (165 degrees C).

Step 2
Cut about 1/2-inch off top of garlic head. Trim root, so garlic sits flat. Remove outer layers of papery skin, leaving enough so cloves remain intact.

Step 3
Place garlic into a small baking dish, drizzle olive oil on top, and cover with a lid or aluminum foil.

Step 4
Roast garlic in the preheated oven until cloves are soft and fragrant, about 1 hour.

Step 5
Stir brown sugar, pineapple juice, water, teriyaki sauce, and soy sauce together in a saucepan and bring to a boil; reduce heat to low and keep at a simmer.

Step 6
Squeeze sides of garlic until pasty roasted garlic emerges.

Step 7
Measure 2 teaspoons roasted garlic into the saucepan and whisk until incorporated. Reserve remaining roasted garlic for another use.

Step 8
Stir lemon juice, onion, bourbon whiskey, pineapple, and cayenne pepper into sauce. Bring to a simmer and cook until liquid reduces by half and turns thick and syrup-like, 40 to 50 minutes.
