I think I love them so much because they have so much flavour, and in the past crisps were my major downfall so maybe it's all in the mind???
There is a thread on this site of recipes using your packs, take a look there are loads of fab ideas. I wouldn't recommend you using greese proof paper though for the crisps, just use a large plate as they stick to the paper.
It's amazing how many things you can make. So far I have got the crisps and muffins down to a fine art and now i'm venturing onto chocolate truffles!! Fab
