The recipe is from Kraft. The citrus flavors are wonderful with this spicy and moist tenderloin. The original recipe calls for a chipotle barbecue sauce; however, a diced chipotle in adobo can be used or chipotle ground chili powder. There are 2 cooking methods as when I originally made this the grill wasn't doing its job. Either on the grill or in the oven this is a wonderful recipe.
