Steak with cheesy topping

Add the butter and flour to a pan to make a roux (sauce), add the milk whisking as you go, then add the cheese, mustard, Worcester sauce and stir until melted. Lastly beat in the egg yolk.

Season the steak with salt and pepper then add to a preheated pan, cook for 3-4 minutes per side for medium, or couple of minutes either way for rare or well done steak. Top with the cheese mixture and cook under a pre heated grill set to its highest setting and cook until topping is golden and bubbling.

Peel and chip the potatoes, keeping them chunky. Parboil for 5 minutes then drain. Transfer to a preheated baking tray then drizzle with oil and bake in an oven set at 200c (gas mark 6) for around an hour until golden. Season with salt.
