#115 Xanthan gum is used to keep fat recipes; does it alter the taste? Can I add xanthan gum to it to hold in the oil that seeps out of keto baked goods?

Xanthan gum is beneficial as an emulsifier to hold fat and to add air giving texture to baked goods. If you add too much it results in a chewy texture. Take a look at the High Fiber Rolls in our Recipe link to see how much Xanthan gum is used compared to other ingredients.
