Tart celery vinegar

Turns meh roasted vegetables into pure decadence and adds a big flavor boost to salad dressings. I once ran out of ACV in the middle of making pickled onions and used some of this to finish the job—I will never eat pickled onions that good again (this bottle is $30 so I can’t actually endorse its use in making pickles but WOWOWOW were they good)
