β Agar Agar (Best Vegan Option)
1/2 teaspoon agar agar powder per 1 eggAgar agar is a plant-based polysaccharide extracted from seaweed that gels liquids when boiled and cooled. It can mimic the setting properties of eggs by forming a firm gel that holds the panna cotta shape.
For best results, dissolve agar agar in boiling liquid and simmer briefly to activate gelling properties. Agar sets more firmly and less elastically than gelatin, so adjust quantity carefully to avoid an overly stiff texture.
The final panna cotta will be firmer and less creamy than with eggs or gelatin, with a slightly different mouthfeel, but it is an excellent vegan alternative.
