Place beef fat (can substitute with duck fat or ghee) into each of the Yorkshire moulds and place in a pre-heated 190 C oven for 2-5 minutes. When oil is hot, remove tray from the oven and pour pudding mix into each mould about three-quarters full.
Bake in the oven for 20-25 minutes until golden and crusty.

When cold, toss in a mixing bowl to rough up the surface.
In a hot pan, fry off the cooked potatoes in duck fat until lightly golden.
