Key Ingredients Guide
- Salmon: Choose fresh fillets with firm, bright pink flesh
- Cod: Look for thick, pearly white pieces for even cooking
- Leeks: Select firm, white stalks with a glossy appearance
- Carrots: Use young carrots for their natural sweetness
- Heavy cream: Full-fat cream ensures the best sauce consistency

Cooking Method
- 1.
- Begin by finely dicing shallots and cutting carrots and leeks into uniform rounds for even cooking.
- 2.
- Slowly sweat the vegetables until soft but not colored, building the aromatic base for the sauce.
- 3.
- Add white wine and stock gradually - wine provides subtle acidity while stock creates depth.
- 4.
- Cook fish gently until it flakes easily but remains moist. Pressure cooking helps retain moisture.
- 5.
- Create a smooth liaison by blending cream, mustard, and flour before incorporating into the sauce.
- 6.
- Finish and serve promptly while the sauce is silky and the fish is at its best temperature.
Success relies on achieving the perfect balance between delicate fish and creamy sauce consistency.

The dish pairs wonderfully with steamed basmati rice or boiled potatoes, which soak up the flavorful sauce.
This modern interpretation preserves the essence of traditional blanquette while creating an elegant seafood variation perfect for any occasion.
