Wash the chive flowers thoroughly and remove as much water as possible. A salad spinner works well, but if you don't have one, lay the flowers out on a clean kitchen towel and press another one down on top of it to soak up the water. Take the flowers off of the stem and put them in a quart mason jar.

Heat the vinegar in a small pot over medium heat just until it is warm. Pour it over the chive flowers in the jar, put the lid on the jar, and allow to steep for at least a week in a cool, dry, dark place. I usually put it in the fridge.

After a week, strain the flowers out of the vinegar, and store the flavored vinegar in a bottle that you can pour easily from and that seals well.

This makes great gifts, too! Just pour it into gift bottles, tie on a bow, and your gift recipients will love it!
