We had friends staying for Christmas and so I bought GF flour to use in cakes/puddings etc. The one cake I made was a failure - apparently because I needed Xanthan Gum. I intended sending the flour back with her but forgot and just found it in the back of my cupboard. Any suggestions for what I could use instead? I googled but only things I saw were also specialist ingredients. I'm avoiding supermarkets as fed up of people Ignoring distancing guidelines. so wondered if there is anything else we can use with it for baking. or use it for without Xanthan gum ? No GF requirements in our house. (I don't know anyone else GF to give it to else would)
