Lemon Thyme Vinegar

With a vegetable peeler, pare a thin spiral strip of peel 6 to 8 inches long from lemon. With a chopstick or wooden skewer, push lemon peel and thyme into a clean 12- to 16-ounce bottle. Fill bottle with white wine vinegar (vinegar should cover herbs completely) and seal. Store in a cool, dark place at least 1 week or up to 4 months.
