O’Toole says: “Enter the collab of the century: prawns and jacket potatoes. You might be partial to a basic bit of prawn cocktail on your spud, but I’ve amped it up by taking some of the flavours of a New Orleans po’ boy and creating the shrimp potato of dreams. If you need me, I’ll be sat alone in the corner demolishing one of these beauties.”

Serves 2

Ingredients

2 baking potatoes neutral oil
100ml buttermilk
1 teaspoon smoked paprika
1 teaspoon dried mixed herbs
1 teaspoon garlic granules
1 teaspoon onion granules
½ teaspoon ground black pepper
8–10 raw, deveined prawns
50g plain flour
few knobs of butter

For the coleslaw

⅛ small red cabbage, thinly shredded
⅛ small white cabbage, thinly shredded
½ carrot, peeled and julienned
2 teaspoons white wine vinegar
2 teaspoons olive oil
small handful of flat-leaf parsley, leaves chopped
small handful of chives, chopped
salt and black pepper

For the sauce

2 tablespoons mayo
1 tablespoon ketchup
squeeze of lemon juice
dash of Tabasco
dash of Worcestershire sauce

Method

Heat the oven to 220°C/200°C fan/425°F/Gas 7.

Rub your potatoes with oil and a good amount of salt, and pierce them all over with a fork. Place them on a rack in the middle of the oven and bake for about 50–60 minutes, until tender on the inside and crisp on the outside.

While the potatoes are baking, make the coleslaw. Mix together all the veg in a bowl. In another bowl, combine the white wine vinegar, olive oil and herbs. Pour the dressing over the cabbage mixture and turn to coat. Season to taste with salt and pepper and set aside for later.

Make the sauce by mixing together all the ingredients in a bowl, seasoning with salt and pepper, then tasting and adjusting the ingredients to your preference. Set aside.

Once the potatoes are almost ready, season the buttermilk with salt and pepper and ½ teaspoon each of the smoked paprika, dried mixed herbs, garlic granules and onion granules, and ¼ teaspoon of the ground black pepper, then tip in the prawns. In a bowl, combine the flour, a big pinch of salt to season, and the remaining smoked paprika, herbs, garlic and onion granules, and pepper.

Pour your oil into a deep-fat fryer or a heavy-based saucepan (don’t let it come more than halfway up the inside of the pan). Place the pan over a high heat and get the oil to 180°C/350°F on a cooking thermometer (or use the thermometer in your fryer).

Sprinkle 1 tablespoon of the seasoned buttermilk into the flour and stir to form some clumps that will go super-crispy. Shake off the excess buttermilk and, in batches, coat the prawns in the flour and fry for about 1–2 minutes, until golden brown, crispy and cooked through. Set each batch aside to drain on kitchen paper while you fry the remainder, then season lightly with salt.

Slice the jacket lengthways down the middle, open it up slightly and fork in the butter to melt. Top with a large dollop of the coleslaw, and crown with a few of those crispy prawns and a drizzle of sauce.
