This is a tamarind pod.
Inside, the pod has a paste-like brown fruit around its seeds.
It doesn’t look particularly appetizing.
The fruit is very sour, but not like a lemon. There’s sweetness there too. It tastes almost like Crystal Light powder. But more delicious.
You suck the fruit away from the seeds. They’re hard, and clack together in your hand, almost like heavy coffee beans. Delicious.
