1. See 2.1 Etymology. Tamarind translates to Indian date. Honestly I don't knew if its actually from the date family, but what I was saying is that the word tamarind lets you know that it doesn't come. from prunes as I originally thought.
2. I was referring to the sauce that Syrians call Tamarindi. I was saying that our sauce comes from prunes although the name connotes that it is derived from dates.
