Sole a LA Normande
Ingredients
Directions
Poach the sole
Place the cleaned sole in a fish kettle that fits it well.
Add butter, parsley, thyme, onion, white wine, water, salt, pepper, nutmeg, oysters, mussels, and truffle slices.
Cover and simmer until the sole is partly cooked.
Make the sauce and serve
Remove the sole and place it on a fireproof dish with some butter, surrounding it with oysters and mussels.
Prepare a white stock and mix it with the fish gravy, heating gently without browning.
Thicken the sauce with the beaten yolks of two eggs and pour it over the fish.
Garnish with truffles, croutons, and button mushrooms, and add a squeeze of lemon.

What each ingredient does
- Butter
- Adds richness and a silky mouthfeel to the poaching liquid and sauce.
- Egg yolks
- Thicken the sauce as they set gently with heat, giving it body.
- White wine
- Adds acidity and aroma to the poaching liquid, lifting the delicate fish flavour.
- White stock
- Forms the savoury base of the sauce, adding depth and body to the gravy.
- Oysters
- Contribute briny, savoury flavour to the fish and the sauce.
- Mussels
- Contribute briny, savoury flavour to the fish and the sauce.
The step that matters
Thickening the sauce with egg yolks. Egg yolks thicken through gentle heat, but if the sauce gets too hot or boils, the proteins curdle and the sauce turns grainy. Heat the stock mixture gently and keep it below a simmer when adding the yolks.
