I use Doves Farm® for the gluten free self raising white flour.
Did it with more cheese as well and added 1tsp of lemon pepper instead of the mustard powder. Good result. - 19 Sep 2014
I made these scones at the weekend and as far as gluten free baking goes, they were pretty good. I added more cheese than stated and used my own mixed herbs but pretty much followed the recipe. They were a little dry/grainy but that's due to the flour I used. I will happily make them again but experimenting with different flours. - 25 Feb 2014
It's not easy to bake with gluten free flour but after lots of apprehension I gave it a go. It's actually really nice recipe although I added 2 whole eggs helping the dough to bind together. Did 12 small scones and after 18 min they were nicely puffed and golden. When I cut through one they were fluffy and crunchy. I could still taste the different flour even I added more cheese. Would I do them again? Yes I would if I had to. - 23 Aug 2015
