Oysters Au Gratin

Rinse spinach, trim and blanch in a pot of boiling salted water for about 2 minutes. Drain, rinse with cold water and squeeze excess liquid. Then finely chop. Peel shallot and finely chop. Heat butter in a pan, sauté shallot until soft, add spinach, mix and season with salt, pepper and nutmeg. Remove from heat.

Preheat the oven broiler.

Heat cream in a pot, add gruyère and slightly melt while stirring. Add creme fraiche and stir.

Open oysters and place in a pan sprinkled with sea salt. Cover each oyster with approximately 1 tablespoon spinach and cover with cream-cheese mixture. Bake under the preheated oven broiler, watching carefully, for about 5 minutes.
