hi my recipie is wait till they are hard and scrape the shell and the white pith off ,roughly chop or bash and then put in food processer and blend into flour on thier own it doesnt rise much but they do make very good biscuits. Or you could try doing them the roman way, boil in shells for 20 mins when soft peel the pith comes off as well then mash add pepper salt other nuts,seeds or fruit and a bit of milk and mix into a gruel my favorite!! regards rob
