Vegan Gelatin Substitute Calculator

How this works

Agar agar is a seaweed-derived setting agent that gels far more strongly than gelatin gram for gram — commonly cited as roughly 2 to 3 times as powerful. That means substituting agar agar powder 1:1 for gelatin powder would produce a noticeably firmer, more rubbery set than intended, so recipes typically call for about a third to a half of the amount of agar powder compared to gelatin. Agar flakes are less concentrated than powder, so they're used closer to a 1:1 ratio by volume with gelatin powder. Pectin, by contrast, isn't a direct substitute at all — it needs sugar and acid to set and is used for fruit preserves rather than as a general gelatin replacement.
