This is a common brand of agar-agar powder found in our local supermarket. I bought it in J.B (Malaysia) at RM2.30/pack (10g).
Agar-agar is a Malay word, it means jelly.
It is a vegetable gelatin, one with high gelling properties and used by vegetarians because true gelatin is made from calf's feet.
Like ordinary gelatin, agar-agar powder is flavorless and becomes gelatinous when it's dissolved in water, heated and then cooled.
