1. Remove the outer skin of the garlic, exposing the garlic cloves. Pick up the middle pillar and cut off the roots. Put it in a bottle and add part of the vinegar.
2. Pour in the sugar and salt, and finally add the remaining vinegar until the garlic is completely submerged. Cover the lid, keep it tightly closed for about one month, uncover, take out, and eat.
Vinegar should be surpassed with garlic, and all seasonings can be adjusted according to your own taste.
