Rinse the flowers gently. Let them dry on a towel or gently pat them dry.
Fill a clean pint jar or other container with the chive flowers.
Pour 2 cups of vinegar over the flowers. Press the flowers down with a clean spoon to make sure they are submerged in the liquid.
Cover the jar with a plastic or glass lid and label with the name and date.
Store away from direct sunlight for 1-2 weeks. Shake the jar daily.
After the vinegar is finished infusing, strain out the blossoms using a fine-meshed strainer or cheesecloth.
Discard or compost the flowers and pour your beautiful pink vinegar into a clean bottle or jar.
