I made homemade gf pizza last night, using Doves farm selfraising white flour (which has xantham in it) and I added a 1 tsp of xantham as well. The topping was Sacla sun-dried tomato pesto, sliced bell-pepper, sliced mushroom, pimiento olives, sliced Spanish chorizo, and grated mozzarella cheese. I have eaten all those products before without any reactions. I found I got that familiar 'full' (as in heavy and gassy) feeling after one slice. I was then bloated and gassy for the rest of the night, but unusually for me (DH) I didn't get the itchy skin reaction. However, today I had a quarter of a slice cold from the fridge and I'm still itching over an hour later and the familiar blisters are popping up.
This is the first time I've baked with xantham gum, and the additional 1tsp was in error as I was following a recipe and forgot that the Doves selfraising already contained xantham...I have read elsewhere that it is not uncommon for coeliacs to be sensitive to xantham. Particularly in terms of bloating and gassy and itchy reactions. Anyone else had this?
