Xanthan Gum is a plant-based thickening and stabilizing agent.
In the world of gluten-free baking, xanthan gum plays the crucial role of imitating gluten. In baking, gluten is what makes dough "doughy." It gives the dough elasticity. Xanthan gum is what holds a cookie or muffin together in recipes that do not contain gluten. If you are blending your own flour, xanthan gum is a must.
