Fish slow-cooked with mustard and dill embodies the elegance of French cuisine. This dish, prepared with care and attention, reveals the depth of flavors of sea bass, highlighting its delicate texture and rich aroma. Cooking in parchment preserves the fish's juiciness, while the combination of Dijon mustard, fresh dill, and lemon adds a refined zest. A sauce based on crème fraîche with hints of ginger and white wine complements the dish with subtle nuances. It is perfect for a cozy dinner or as an elegant festive treat. The presentation of the fish, neatly layered and topped with velvety sauce, transforms the meal into a true gastronomic delight.

Season with salt and pepper. Rub the outside of the fish with 1 tablespoon of oil. Fill the cavity with ginger, lemon, and dill mixture.
