I will tell a little about the usual fruit made for the ingredients of tamarind in cooking seasoning vegetables people here call sunti acid.
well the way of making it easy first picked the first bamboo and dry to dry and think the fruit is a bit wilted then take a salt to taste then mixed with sunti acid was continued to dry up drying time of 7hari until the color to black then if it can be used store in the cupboard ice so it's not easy to change.
