Devilled kidneys on toast was very popular in the past although you don’t see it as often now. Its a pity as the taste is excellent and a wonderful breakfast. If you are squeamish about offal, it may help if you chop up the livers very small.
You will need:
Lambs kidneys (Use veal kidneys for a richer taste)
a white onion
garlic cloves
fresh parsley
English mustard (dry or pre mixed)
Worcestershire sauce
Chilli powder or cayenne pepper
Double or heavy cream
oil or dripping
salt and pepper
Personally I’d skip the brandy and toast, but this a great step by step video
