Ingredients

• 400 g Atlantic cod ( cut into large cubes )
• 200 g Shrimp ( peeled )
• 200 g Scallop ( cleaned )
• 60 g Minimum butter sweet
• 50 g Wheat flour
• 500 ml Whole milk
• 100 ml Cream
• 100 ml Dry white wine
• 2 piece Shallot ( finely minced )
• 100 g Emmental cheese ( grated )
• 30 g Breadcrumbs
• 1 pinch Nutmeg
• 1 pinch Gray sea salt
• 1 pinch Black pepper ground

Instructions

1. Seafood preparation

   Cut the cod into 3 cm cubes. Clean the scallops. If using whole shrimp, peel them properly. Everything must be dry before cooking to avoid releasing excess water.

2. Sauté aromatics and deglaze

   In a pan with a knob of butter, sauté the minced shallots without browning. Pour in the white wine and reduce by half over high heat. The alcohol smell should disappear, leaving only the grape aroma.

3. Make the sauce and singer

   Add the remaining butter, let it melt, then pour in the flour (singer). Whisk for one minute. Pour in the cold milk all at once and whisk until the sauce thickens and coats the back of a spoon. Add cream and nutmeg.

4. Assembly and browning

   Place the raw seafood in a gratin dish. Pour the hot sauce over it. Sprinkle with emmental and breadcrumbs. Bake at 200°C until the top is deep brown and the sauce bubbles around the edges.

Chef's tips

• Do not pre-cook the seafood; they will cook perfectly in the sauce in the oven and remain tender.
• If the sauce is too thick, loosen it with a little bit of shellfish cooking liquid if available.
• Use an earthenware or cast-iron dish for thermal inertia to keep the dish warm at the table.

Storage

Store in the refrigerator for 24 hours. Reheat gently in the oven at 150°C to avoid overcooking the fish.
