Agar vs Gelatin: what is the difference?
How they differ
from source
Agar is the plant answer to gelatin and it does not behave the same way. Agar is a polysaccharide from red seaweed; gelatin is hydrolysed animal collagen, a protein. Agar sets much firmer, holds at room temperature, and only melts around 85 degrees Celsius, which is why it is the standard medium for growing bacteria in a warm incubator where gelatin would liquefy. Gelatin melts near body temperature, which is precisely why it feels the way it does in the mouth and agar does not. Agar also sets at a much lower concentration for the same firmness. For a vegetarian or vegan recipe, agar is the substitute, but it is not a like for like swap in texture.
