Tamarind

Tamarind was a tree that produced edible brown-orange leguminous fruit that was consumed as a spice. To taste, tamarind could be similar to quelaerel, a sauce made out of threeb, a leech found in Abyssal layers, such as Gaping Maw, Slugbed, and Shedaklah.

Availability
Tamarind was grown and mashed into a spice paste in the lands of Calimshan and Tashalar, renowned for their strongly flavored cuisine. From there, tamarind was traded, being moved through the locations on the Trade Way of Amn and Tethyr. Through trade, tamarind was available in the caravan stop towns, such as Mosstone.

Tamarind paste was widely available via Aurora's Whole Realms Catalogue and was sold in the "Exotics" section for 100 gold coins per ounce.

Tamarind has a more or less usual presence further to the south-east of Faerûn, a lot of folks carried spice pouches as they traveled. Such spiced included dried powdered tamarind, dried ginger, tumeric, ground almonds, as well as raisins and rosemary.

Usages
Tamarin was a cooking ingredient used for its warm spicy flavor. For example, in Mosstone, tamarind was used to create bite-sized sugar-dusted pastry known as tamarind balls. They were available from the Drover's Last Drink tavern and loved by Volothamp Geddarm. Another example of tamarind use in cooking was the always-popular eggfry bread, always savory egg-soaked toast fried and consumed, oftentimes by traveling merchants. The fried bread was often drenched in gravy, fat drippings, and spicy sauces, namely, tamarind sauce.

Tamarind was known to be used in medicine for its infection-preventing properties and especially handy against gangrene.
