Came across this the other day and thought I would share. Sounds almost like a teriyaki style marinade/glaze. I haven't tried it yet but it seems pretty interesting .... 3 cups pineapple juice 1 1/2 cups brown sugar 1 1/2 tablespoons mustard powder 1/3 cup ketchup 1/3 cup red wine vinegar 1 1/2 tablespoons fresh lemon juice 2 tablespoons soy sauce 1/2 teaspoon ground cloves 2 teaspoons ground ginger 4 cloves garlic, minced 1/2 teaspoon cayenne pepper 1 (2 pound) slab baby back pork ribs 1.In a large glass bowl or dish, stir together the pineapple juice, brown sugar, mustard powder, ketchup, red wine vinegar, lemon juice and soy sauce. 2.Mix in the cloves, ginger, garlic and cayenne pepper. 3.Place ribs in marinade, cover and refrigerate for 8 hours or overnight. 4.Remove ribs from marinade, retaining marinade. 5.Heat marinade over medium high heat until boiling. 6.Reduce heat and cook until thickened. 7.Smoke ribs using your preferred method and finish with the marinade/glaze.
