Place shallots, salt, pepper, garlic powder, and honey in a half pint mason jar. Pour vinegar on top and screw lid on. Shake to combine. Store in fridge.
Notes
You can substitute Champagne vinegar for red wine vinegar, pinot grigio vinegar, or rice wine vinegar.
Store in fridge and eat within 1 week.
I like to use the brine as a base for salad dressing - just add olive oil and fresh or black garlic.
