Double two sheets of aluminum per filet. Curl the edges creating a shallow box to allow for adding sauce without dripping.
Season the salmon fillets with a pinch of salt and freshly ground Sichuan pepper.
Pour some olive oil in each of the foil boats, place the seasoned salmon filets, one per foil.
Add lime juice and grated ginger and then crush red peppercorns slightly with your hands and sprinkle over each filet. Place a large sprig of dill on top.
Seal the aluminum foil well by crimping and folding the edges and the twisting and curling up the ends.
Place on the oven rack (without a tray) Bake in the oven around 6-8 minutes, depending how thick the fish fillets are.
Discard the dill, serve with 1 teaspoon of thick cream, sprinkle with some chopped chives and a little Fleur de Sel.
