Step 1You can either peel the outside papery skin from the heads or just cut about 1/2 inch off the tops of each bulb, making sure that each clove is exposed. Place the garlic in a glass jar, add 1 cup of vinegar, cover the jar tightly and set it aside in a cool, dry place for 2 weeks.
Step 2After 2 weeks, drain the vinegar from the garlic.
Step 3Combine the soy sauce, water, sugar and 1/2 cup of vinegar until the sugar is completely dissolved. Pour over the garlic. Cover and let sit another 2 weeks.
Step 4Serve at room temperature or chilled. Refrigerate after opening.
