Powdered black soybean drink mixed with water: Garu Seonsaeng 99.3
Garu Seonsaeng Drinkable Raw Soy Milk Black Soybean 99.3 is a powdered soy drink from Korea that can be mixed with water or milk. I tried it with water and found it mildly nutty, with little bean odor and fewer clumps than expected, though it did not become smooth like ready-to-drink soy milk immediately.
