Is it because you want it gluten free? I once made banana bread with doves farm gluten free plain flour which is a blend of flours and it came out ok. I used a recipe I normally use with normal flour. Th recipe was from mydish, it's called 'best ever banana bread' I think. Though now I use the hummingbird recipe but I haven't tried that GF yet.
Sort of... my DSis is coeliac so I try out recipes occassionally - and she has given me some lovely gluten free recipes. This means that I have rice flour in my store cupboard, and I got to wondering if I could make more use of it (and bake the banana bread for Dsis too).
Thanks for pointing me to the mydish recipe - I'll look at quantities and see if I can work out how to apply it to the AK version .
