The Best of Condiments is Vinegar

The Prophet ﷺ was reported to have once remarked that vinegar was the seasoning of all the prophets who came before him.
Jabir narrated, “The Messenger of Allah, peace be upon him, took me one day with him to his house. He was served some bread. He asked: ‘Is there any dip?’ They replied ‘No, only some vinegar.’ He said, ‘Vinegar is a good dip.’ Jabir used to say, “I have loved vinegar since I heard it from Allah’s Prophet”. Naf’a said, “I have loved vinegar since I heard it from Jabir.”
[Muslim, Abu Dawud, Nasa’i]

What is Vinegar exactly?

The word vinegar literally means sour wine (French derivation). It is basically alcohol that has gone through a chemical process of souring and reached a point where it is no longer alcoholic in nature. This alcohol can be derived from a few things, but most commonly comes from grapes (wine), apples (hard cider), corn or wheat (grain alcohol). How is Vinegar Made?

As just mentioned, vinegar is the result of a process of chemical change which renders the final product to be free of alcohol, even though it starts out from a product which is fermented/alcoholic.
