These are basically macaroons in a biscuit form. You can adapt this recipe by changing the flavors and colours of the biscuits. I was looking around for macaroon recipes, i found one and decided half way through making it to adapt it to make a chewy crisp biscuit.
The mixture may seem runny but it doesn't matter as it means the biscuits will be light. Check out some more of my recipes at Joseph.Castledine
