Gelatin and agar agar powder can be used interchangably in gluten-free recipes, But what are the differences in these gluten-free ingredients and why are they used in some gluten-free recipes?

Using Gelatin and Agar Agar in Gluten-Free Recipes


Most cooks are familiar with gelatin- the stuff that makes Jello gel. You can find it in virtually every market, usually as Knox brand gelatin.

Gelatin is sometimes used in gluten-free recipes to bind and thicken batters and dough. Used in gluten-free pizza crust recipes gelatin makes the dough more pliable and easier to shape without cracking.

Gelatin is processed from animal bone, hooves and connective tissue. It's not suitable for vegan diets.

Agar Agar

Agar agar is a flavorless vegan alternative to gelatin. It is used in processed foods to gel, thicken, texturize and stabilize confectioneries, dairy products, baked goods, sauces and dressings, meat products and even beverages.

Agar agar is processed from red algae into sheets, flakes and powder. The powder and flake forms are easy to work with and are high in proteins and fiber.

Use 1 tablespoon agar flakes to thicken 1 cup of liquid. Use 1 teaspoon agar powder to thicken 1 cup of liquid. Follow directions on product packaging for use.
