Agar agar

Agar agar is generated from red algae and functions similarly to unflavored gelatin in thickening and generating a jelly-like texture. Because it is plant-based, agar agar is an excellent vegan substitute for gelatin. It is often sold in the form of flakes, sheets, or powder.

Agar agar can be used in place of xanthan gum at a 1:1 ratio. To begin, dissolve it in room-temperature water. For every 1 tablespoon (5 grams) of flakes or 1 teaspoon (2 grams) of powder, use 4 tablespoons (60 mL) of water. Then, cook it over low heat for 3-5 minutes, or until dissolved, and allow it to cool somewhat before using. If it's too thick, liquify it using an immersion blender.
