3 to 4 cloves garlic, smashed
1/3 cup white vinegar
1/4 tsp. black peppercorns, cracked
1 bay leaf
1/3 cup soy sauce
vegetable oil or spray for sauteing
3-4 med. potatoes, cut in 1-inch pieces (optional)

Combine all ingredients in a deep glass or stainless steel sauce pan. Bring to a boil over medium heat, then reduce heat to medium low.

Serve with warm steamed rice.
