Why it works: Potato and butter match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and 6,445 recipes mention both. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Put the Anya potatoes in a pan of boiling water with a pinch of the salt and cook for 15 to 20 minutes until tender. Drain well.
Meanwhile, use a peeler to remove the peel of one orange in thin strips, then juice all three oranges. Finely chop the Romero pepper.
In a small pan, combine the half cup of chicken stock, the orange juice, the orange strips and the caster sugar. Simmer over medium heat for about 8 minutes until reduced by half. Stir in the double cream and simmer 2 minutes more. Keep warm.
Season the trout inside and out with salt and black pepper, then dust lightly with the plain flour, shaking off any excess.
Heat 1 tablespoon olive oil in a frying pan over medium-high heat. Fry the trout skin side down for 4 minutes, pressing gently with a spatula, then turn and cook 3 minutes more until the flesh is opaque and flakes easily. The thickest part must reach 145°F (63°C).
Remove the sauce from the heat and whisk in the 25g butter a piece at a time. Stir in the chopped Romero pepper and keep warm.
Return the drained potatoes to the pan with the 1 tablespoon butter, 2 tablespoons olive oil, the chopped parsley and dill. Crush them roughly with a fork and season with salt and black pepper.
Spoon the crushed potatoes onto a plate, lay the trout on top, spoon the orange butter sauce over and serve.

Fit is the average pairing score against chicken, potato, parsley, olive, pepper, flour, butter. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
