Agar-Agar Jelly — set tropical-fruit jelly
Agar-agar jelly is a Chinese (and Southeast Asian) set dessert made with kanten / agar — the seaweed-based gelling agent — and tropical fruit juices or coconut milk. Unlike gelatin, agar sets at room temperature and gives a firmer, sharper-set jelly that holds shape in heat.
