I have to use gluten free flour so I use whatever I've got.
Today it's half and half gf flour and buckwheat flour, a tablespoon of ground almonds and porridge oats. I'll scatter demerara sugar over the top before popping it in the oven.
I opened my sweetie jar that holds my Plain flour and it was full of weevils (urgh,yuk) so had to bin the lot, I used SR flour instead and it was fine, no different than usual. I use the River Cottage recipe though with oats and ground Almonds in it, so that might make a difference.
