Scandi-Style Roast Salmon

Meanwhile, heat a drizzle of oil in a small saucepan on medium heat. Add the shallot with a pinch of salt and cook until softened, 4-5 mins. Once the potatoes are cooked, drain them in a colander, return to the saucepan with the soured cream, the vegetable stock powder, water (see ingredients for amount) and half the dill. Add the cooked shallot and plenty of salt and pepper. Gently mix and transfer into a baking dish. Bake on the top shelf of your oven until bubbling and golden, 20-25 mins.

Put the vinegar, sugar, water (see ingredients for amount) and a large pinch of salt in a small saucepan over medium heat. Cook until the sugar and salt have dissolved, 1-2 mins. Trim the cucumber. Use a vegetable peeler to peel long ribbons from all sides of the length of the cucumber. Stop when you get to the seeds. Pop the cucumber into a mixing bowl and pour over the vinegar mixture, add the remaining dill and mix well. Set aside while you cook the salmon.

About 15 minutes before the gratin is done, mix the mustard and honey with a drizzle of oil and a pinch of salt and pepper. Pop the salmon on a tray lined with baking paper and spoon the mustard mixture over, spreading with the back of a spoon to evenly cover the salmon. Bake on the middle shelf of your oven for 12-14 mins. IMPORTANT: The fish is cooked when opaque in the middle.

Once the gratin is done, leave to stand for 5 mins before serving. Pour off any excess liquid from the cucumber.
