Why it works: Lobster and sauce are a kitchen classic. They rank in the top 6% of all ingredient pairs, and 1,095 recipes mention both. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Fillets of Sole a LA Rouennaise
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Remove both skins from the soles and fillet them.
Spread some lobster cutlet mixture on one half of each fillet and fold it over.
Place the fillets on a greased baking sheet and sprinkle with lemon juice.
Bake and serve
Cover with buttered paper and bake in a 350°F (175°C) oven for 7 to 12 minutes, depending on thickness.
Dish the fillets in a circle and pour over the sauce mixed with chopped truffle.
Decorate with alternating pinches of chopped truffle and prepared lobster coral.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soles
- Forms the delicate fish fillets that gently cook and flake when baked.
- Lobster cutlet mixture
- Adds a rich, savoury filling that moistens the fish as it cooks.
- Velouté sauce
- Provides a smooth, creamy sauce that coats the fillets and adds moisture.
- Finely chopped truffle
- Contributes a strong, earthy aroma to the sauce and garnish.
- Lemon juice
- Adds acidity that brightens the flavour of the mild fish.
The step that matters
Baking time by thickness. Fillets cook quickly and dry out easily, so the time must match thickness. Overcooked fish becomes tough and loses its moisture, while underbaked fish stays opaque and unsafe to eat.
