Agar tastes bad and can't be frozen in the refrigerator. It has a strange smell, but it can be used for sweets and salty food. Jelly powder is elastic, suitable for making sweets, and gelatine powder is also elastic, so it can only be used as salty food. I recommend you to make pudding powder for dessert. This thing smells delicious, but it is colored and salty, so we use Kara tape, which is used in our hotel. Friendly reminder not to eat more of these things. They belong to edible gum.
