For those with, and those cooking for those with, allergies...
55g Plain Flour
30g Ground Arrowroot
30g Tapioca Flour
350ml Soya Milk
Bung it all in a bowl and mix well! These are UK pancakes so pour a small amount into the frying pan and flip over when underside is browned - you're aiming for something thin, like a French crepe.
Surprisingly these taste a lot like real pancakes, perhaps just a little more crumpet or bread like... maybe? Very close the the real thing anyway.
I also used this mixture (doubled) for toad in the hole (8 sausages). Didn't cook it quite long enough but it seemed like it would probably work well if I had done.
