Start with the pickle. Bring a small saucepan of water to the boil on a medium-high heat. Add the mustard seeds and blanch for 30 seconds. Drain in a sieve, then fill the pan with fresh water again and repeat this process twice more. This’ll remove any bitterness from the seeds.

In a medium bowl, whisk together the vinegar, sugar and ¼ teaspoon of salt to dissolve, then add the mustard seeds and cucumber and toss to combine. Set aside to pickle lightly while you continue with the recipe.

Peel the potatoes and grate them on the coarse side of a box grater. Transfer half the mixture to a clean tea towel and wring out as much liquid as you can. Don’t worry about being too forceful; a little liquid will help it cook through. Transfer to a large bowl and repeat with the remaining grated potato. You should have roughly 600g wrung-out potato. Add the panko, the 2 tablespoons of melted ghee, 1¼ teaspoons of salt and a good grind of pepper and mix well to combine.

Place a large, non-stick frying pan over a medium heat with 40g of the ghee. Once the ghee is melted and hot but not smoking, add the potato mixture, using the back of a spatula to smooth it out evenly. Let it cook and brown gently for 25–30 minutes. Towards the last 5–10 minutes, the rösti will start to detach from the base of the pan and you’ll be able to move it around easily. Carefully invert the rösti onto a large plate, browned side up. Return the pan to a medium heat with the remaining 15g of ghee and, once melted, slide the rösti back into the pan, browned side up. Cook for another 15 minutes, until nicely browned on the bottom. Transfer to a board and cut the rösti into eight equal pieces.

Once the rösti has been flipped, add the red onion to the pickle mixture to soften slightly. Stir through the dill right before serving.

Make the cream cheese by stirring it together in a bowl with the spring onions and a tiny pinch of salt.

Make the everything seasoning by mixing all the ingredients together in a bowl.

Divide the rösti between four plates, with a spoonful each of the cream cheese and pickle mixture and a good sprinkling of everything seasoning, serving any extra alongside.
