Agar-agar is a plant-based gelling agent extracted from seaweed, used as a vegan alternative to gelatin in jellies, mousses, and panna cotta. One metric cup (250 ml) of agar-agar powder weighs around 190 grams or 6.70 ounces. Most recipes call for it by the teaspoon, where 1 tsp weighs about 3.8 grams.

Agar sets firmer than gelatin and can produce a brittle result if overdone. Unlike gelatin, it gels at room temperature and is not affected by heat once set, so small differences in quantity have a clear impact on texture.
