   4                    Heads garlic
   2       c            Red wine vinegar
   2       c            Water
   1       c            Sugar
   6                    Whole cloves (the spice)
   2       tb           Black peppercorns

Preparation:

Separate garlic cloves, but do not peel. Place all ingredients in a large heavy-bottom saucepan. Bring to a boil; cook for 10 minutes, stirring from time to time. Reduce heat to moderate and cook 5 minutes. Cool to room temperature. Transfer to a large glass or ceramic jar large enough to hold garlic and the liquid. Tightly seal. Refrigerate at least 1 month before serving. The garlic improves with age for as long as 15 years.
