Difference between agar-agar and gelatin
The main difference between agar-agar and gelatin is from where they are derived. Whereas animal-based gelatins are made from animals, agar-agar is vegan, coming from the red algae plant. Also, when cooking with agar-agar, it needs different preparation. For example, agar-agar needs to boil to set, while gelatin can simply dissolve in warm water.
