I make them, but I don't really have a recipe. Maybe two heaped tablespoons of plain flower, two eggs. Whisk until smooth, add milk to get a double cream consistently. Salt and pepper. Leave to rest . Heat your oven to high. Put your pan in the oven , add fat of your choice. when your fat is smoking hot, add your mix whilst the pan is in the oven. Leave for approximately 20minutes, don't open your oven door!
Mine never rise like the ones in magazines. I know I am probably impatient and don't let the fat get hot enough, and am a bugger for opening door to check lol I remember the yorkshires we used to have at school - they were a flat tray bake cut into squares
