I have just recently been diagnosed with gluten intolerance and with baking season upon us I have a question for you. I have King Arthur gluten-free flour in the blue bag and I would like to use it in some of my regular cake recipes. I had read on another website that I need to add 1 teaspoon of xanthan gum per cup of flour in order to make the recipe come out OK. However your blog suggests that I need to add only 1/4 teaspoon xanthan gum for every cup of flour. Is King Arthur flour different than other gluten-free flours? So I would like some advice on how much Xantham gum to add for every cup of flour needed the cake recipe.
