A dear friend just introduced me to Tamarind. He gave me some seeds to plant, and one sample to taste. Honestly, I don’t think I’ve heard of “it” before so searched the Internet for information.
What the hell is Tamarind? was the first one I read (because of the title).
Of course, Wikipedia provided additional information.
California Rare Fruit Growers has this to say.
Dr. Mercola writes What is Tamarind Good For. (I want to know the health benefits.)

Texas Planting Zones. (Will it survive in Livingston, Texas?)
Dave’s Garden precludes my zone (8b) in his description.

That was interesting!! One day, soon, I’ll plant the seeds my friend gave me. “Nothing ventured, nothing gained.”
Three Quarters & Counting 
I remember tasting a tamarind in the Bahamas years ago and thought it tasted like the fruit in A-1 sauce
