All instructions and excellent step by step photos are on a sit called "The Pink Whisk"
A friend said the following:-
"We've made these using pure sunflower spread and rice flour. They are really yummy, Finley adores them. We've frozen them individually, defrosted over night and then put in the microwave for 20 seconds just before eating and they are nice and soft. I did try to defrost in the microwave and they burnt to smithereens!"
