it's a snack mixed with soft tofu, sweetened syrup made from brown sugar, water and vanilla, and sago pearls (kinda like tapioca pearls in bubble tea~), they're much smaller tho ^^
Silken tofu is steamed and the other ingredients are brought to be boiled. Afterwards tofu is placed in a cup then syrup and pearls are poured. It's mixed together and best served warm.
