I just bought some fresh Tamarind & was told that I can eat the Tamarind seeds. Are they really edible? How would I prepare them if so?
They're certainly edible, but you might have to work for it.
A Western view from Purdue CropINDEX:
People from more native cultures are perhaps more willing to put in the effort:
I also found a few other mentions of them being a snack food, something people had eaten at home, like this one, which also mentions roasting and de-shelling in bulk with a grinding stone.
As for how to prepare them, I think your best bet might be to roast them, peel with the aid of a mortar and pestle (to crack them open), then soak for overnight or for a day in buttermilk like this recipe suggests. It's worth looking at the full recipe - there's more detail and a little background.
You can certainly try them before soaking as well, if you're looking for something that takes work to eat - you might have to suck and chew a while. As the recipe SAJ14SAJ found says, and says "This is the real test for teeth as it is very hard and crunchy."
Yep, they are edible and I am eating them right now. They are roasted untill they turn black charcoal colored and then peeled. The kernel smells a bit like coffee bean. They are very hard to bite, so they must be kept in the mouth for some time mixing with saliva and eaten slowly.
It helps people who have a habit of constant nibbling, so they can engage their mouth and at the same time have a cholesterol free, slow to eat, healthy snack.
According to Plant Cultures,
Finding recipes that address removing the very tough seed coat is difficult, especially since there are false hits for the flesh or pulp of the fruit, as well as many non-culinary uses. Here is one set of instructions.
