How to Make black pepper crusted pork tenderloin

This succulent dish has all the things I love in a recipe; an easy piece of meat to work with, a super simple sauce that tastes like something that took hours, and the classic flavor combination of hot/tangy with sweet/fruity. Ingredients needed are pork tenderloin, garlic clove, white vinegar, chicken stock, black cherry preserves, salt, cracked black pepper and butter.

1 pork tenderloin (not loin)

1 clove garlic

1/3 cup white vinegar

1 cup chicken stock

1/2 cup black cherry preserves

salt to taste

lots of cracked black pepper

2 tbl butter
