Djon djon mushrooms are gathered wild, not farmed, then dried; only their dark soaking liquid colors the rice, and the tough mushrooms themselves are often strained out.
Rice is cooked in the dark, earthy soaking liquid of dried black djon djon mushrooms until it turns a deep grey-black, giving off an aroma close to truffle. Street cooks ladle it onto plates alongside fried fish or griot from big pots at market stalls.
