This is a variation on the traditional pickled salmon sold in every Jewish delicatessen. The difference: The salmon is more delicate and less vinegary, and has a richer color. It makes a perfect Sabbath luncheon dish.

Ingredients:
6 skinless center-cut salmon fillets (about 6 ounces/170 g each)
1 teaspoon extra virgin olive oil for greasing the pan
Kosher salt
Freshly ground black pepper

Preparation:
Preheat the oven to 200 F (95 C). Grease a glass or enamel-lined baking pan that can hold the fillets in a single layer.

Pat the fillets dry with paper towels and season them lightly on both sides with salt and pepper. Place them in the dish and bake, uncovered, for 25 to 30 minutes, or until cooked to your taste.

Remove the baking pan from the oven, cover with foil, and let cool completely. (The fish will continue cooking outside of the oven.)

MARINADE
Ingredients:
3 tablespoons extra virgin olive oil
4 tablespoons rice vinegar (for Passover, replace with white wine vinegar)
1 1/2 teaspoons salt
Freshly ground black pepper
1 small red onion, very thinly sliced (see note below)
15 dill sprigs, snipped finely with scissors, plus 2 sprigs, snipped, for garnish

Preparation:
In a medium bowl, whisk together the olive oil, vinegar and salt. Add pepper to taste. Pour the marinade over the salmon, add the onion and sprinkle with the 15 snipped sprigs of dill.
Cover the dish with wax paper, then foil and refrigerate for 2 to 3 days without turning.

To serve: Bring the salmon to room temperature. Place on individual plates along with some of the marinade and onions. Garnish with the fresh snipped dill; makes 6 servings.

Note: I use a mandoline to slice the onion, as it makes the cutting easier.
