Agar Agar substitutes

Out of agar agar? Here are the best substitutes — what to reach for, why it works, and how much to use. Gelatin is the top pick.

  1. 01
    Gelatinbest pick

    Same gelling role; not vegetarian, sets softer and more wobbly.

    start 1:1 by volume, then adjust

  2. 02
    Carrageenan

    Also seaweed-derived and vegan, with a more tender set.

  3. 03

    Vegan gelling agent for fruit preserves and glazes.

  4. 04
    Cornstarch

    For thickening only — it will not set a firm gel.

    2 tbsp per cup liquid

How we choose these

These are tested kitchen substitutes, chosen for matching flavor, texture, and role — with ratios so the swap actually works. Taste as you go; substitutes shift intensity, not just flavor.
