i just made potato salad, and even though i don't normally use vinegar, i know a lot of recipes do, so i threw a splash (less than a tablespoon) in at the last minute. it was a previosly unopened bottle of honey wine vinegar that i got as a gift, i'm not sure when.
i put it in while the potatoes were still hot, right before putting it in the fridge, but now it smells VERY strongly of the vinegar. it it just because it's still hot? or could the vinegar have gone bad?
