SAUCE
¼ Cup Lemon juice
¼ Cup Butter
¼ Cup Ketchup
¼ Cup Worstershire Sauce or Soy Sauce
¼ Cup Vinegar
¼ teaspoon Tabasco Sauce (optional)
2” (inches of 2lb bag) Brown Sugar

Melt Butter and add all ingredients but sugar. Stir and bring to a boil. Then add Sugar.

Marinate tenderloin in sauce. Cook tenderloin, either on the grill medium/low heat, or in the oven at 350 degrees and monitor the meats temp. Pour remaining sauce in a sauce pan; bring to boil, then turn to warm. Present sauce as pour over or beverage in my case :yumyum:

I use 2 pork tenderloins for this amount of sauce.
