Remove the core of the apple and using a mandolin or sharp knife thinly slice the apple and place into a bowl with water and lemon juice to stop the apple from going brown

Turn the steaks over and cook for another 10 mins. Don’t worry if the toppings slide off

Once the potatoes are soft drain off the water and return to the same pan. Add 30g salted butter, wholegrain mustard, salt and milk. Mash until smooth

Remove steaks from the grill and turn them again. Add the sliced apple and spoon over the sugar syrup and place the steaks back under the grill until the apples are caramelised

To plate, add mustard mashed potatoes to the plate and place the steak onto the mashed potatoes. Serve with sides of choice and enjoy
