Lemon fish, spuds & spinach sauce

Scrub the potatoes, chop into 1cm cubes, place in the large air-fryer drawer and toss with 1½ tablespoons of olive oil and a pinch of sea salt and black pepper. Cook for 20 minutes at 200ºC, or until golden, shaking halfway.

Place the cheese, horseradish, soured cream, half the spinach and most of the dill, stalks and all, in a blender with 50ml of water. Squeeze in a quarter of the lemon juice and blitz until smooth, then season to perfection. Remove the shelf from the small drawer, then pour in the sauce and replace the shelf.

Season the fish fillets and place in the small drawer. Finely slice 4 rounds of lemon, place on top of the fish, spritz with oil, and cook for 12 to 15 minutes at 170ºC, or until the fish is just cooked through and the sauce is hot.

Tip the potatoes out of the large drawer and pack in the remaining spinach. Cook for 2 minutes at 200ºC, or until just wilted, while you remove the fish from the small drawer so you can divide the sauce between plates. Arrange the fish, spuds and wilted spinach on top. Pick over the reserved dill and finish with a drizzle of extra virgin olive oil, if you like.
