Gelatin to Agar-Agar Conversion: Use 1 tsp (2.3g) Agar-agar powder (pure) + ¼ cup (60g) Water or recipe liquid to dissolve
To replace 1 tbsp unflavored gelatin powder (7g packet), use 1 tsp (2.3g) Agar-agar powder (pure) + ¼ cup (60g) Water or recipe liquid to dissolve (best for vegan panna cotta, fruit jellies, vegan marshmallows, and mirror glazes). Replace animal-derived gelatin with plant-based agar-agar powder in jellies, panna cotta, and glazes.
Scaled Substitution Options
Agar-Agar Powder (1:3 Potency Ratio)
Balance: MUST BE BOILED: Whisk agar-agar into liquid and boil vigorously for 2 to 3 minutes to activate its gelling properties.
Texture: Sets much firmer and more brittle than gelatin; sets rapidly at room temperature (around 105°F / 40°C).
Agar-Agar Flakes (1:1 Ratio)
Balance: Flakes are less concentrated than powder; simmer for 5 to 7 minutes until completely dissolved.
Texture: Yields a clean, neutral plant-based set with firm hold.

Frequently Asked Questions
Why didn't my agar-agar set? ▾
Unlike gelatin (which dissolves in warm water), agar-agar MUST reach a full rolling boil (212°F / 100°C) for at least 2 minutes to hydrate and activate.
Does agar-agar melt in warm weather? ▾
No! Agar-agar remains solid up to 185°F (85°C), making it ideal for summer buffets where gelatin would melt.
