from my childhood I've always loved the meat product that is a fray bentos steak and kidney pie. no else likes em, and my family hate kidney.
so, when missus went out for a curry with her mates I packed the kids off to bed to make a S&K pie of pies..
here we go:
500g of chopped, fatty steak and an onion, sealed in pan, onions browned off well.... with a touch of colour on the meat.
remove meat, in same pan: 350g of filleted lambs kidney, gently fried in butter, sage and balsamic.
pan "cleaned" with 300ml of water,, then 5 tablespoons of lea and perrins, half a table spoon of bisto and and same of plain flour. 4 teaspoons of english mustard. heat through & stir++
chuck all in a flat pie dish.
closely put prebought sheet of puff pastry on mix & seal onto edges with butter.
low heat oven, intermittently painting milk on the top / foil to stop it burning... about 90 mins.
damn, that was good!
