How to prepare Lamb Kidneys
What's the best way to cut the gristle out of kidneys? I've just done some this evening but found it incredibly fiddly and time consuming cutting out all the little 'branches' from the middle of the split kidneys. Are you supposed to just get the main gristley bit or is there some easy way to cut them all the bits out, and are you supposed to remove the clear membrane from the surface or not?
They were very nice devilled btw.
