Sweet-and-Sour Vinegar Garlic

Why people make this

When the weather swings between sun and rain, anyone run-down or overworked can catch cold easily. A little homemade sweet-and-sour garlic each day is an old standby traditionally taken to strengthen the constitution and help fend off chills. I used to make this with plain rice vinegar; adding rock sugar makes it taste much better, and it’s a friendly thing to keep in the fridge through cold season.
