I tried to make Delia's plain scones yesterday. There were edible but had not risen very much at all.
I can only get plain flour, if I remember correctly you once told me that one of Delia's teaspoons of baking powder to 100g flour is about right. I used 225g plain flour and 4 x 5ml teaspoons baking powder, Is it possible to use too much BP? I could almost taste it in the scones.
I also had another power outage yesterday, only for 10 minutes and that was before I made the scones. So if this is going to become a regular thing, stand by for more me asking for more help!
