Tamarind paste
Tamarind paste is created from tart tamarind fruit, which is not a form of vinegar. It complements many Indian and Asian meals that call for red wine vinegar thanks to its flavor, which is comparable to that of red wine vinegar.
Although it functions best as a meat tenderizer, it doesn't always perform well in recipes. Start with a modest quantity, like a teaspoon or two, and build up from there as necessary because it has a powerful flavor. The availability of tamarind paste may be easier to find than that of red wine vinegar at specialty shops, Asian or Indian markets, or online.
