How much xanthan gum should be added to the recipe?

The amount of xanthan gum to add to the recipe depends on the specific recipe and desired consistency. Typically, a good starting point is to add 1/2 to 1 teaspoon of xanthan gum per cup of liquid in the recipe. It is important to gradually add and mix in the xanthan gum to avoid clumping and achieve the desired thickness.
