1. To make the sauce, toss the cucumber with ½ tsp salt in a sieve and let stand to drain for 1 hour. Rinse with cold water and pat dry with paper towels. Mix the cucumber, yogurt, mustard, scallion, and dill. Season with salt and pepper.

2. Preheat the oven to 400°F (200°C). Arrange the salmon in an oiled shallow baking dish. Brush with oil, sprinkle with lemon juice, and season with salt and pepper.

3. Bake in the oven for 8–10 minutes, until the salmon is opaque when pierced with the tip of a knife. Using a slotted spatula, transfer the salmon to dinner plates. Stir the pan juices into the cucumber sauce. Spoon the sauce over the salmon. Serve hot.

Good with buttered new potatoes and steamed asparagus.

Variation:
