Why it works: Lemon and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 14,037 recipes mention both. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Sole a LA Rouennaise
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the sole
Skin and fillet the sole, then wash and dry it.
Make the lobster filling
In a pan, melt the butter, add the flour, and gradually stir in the stock to make a panada.
Add the chopped lobster to the panada.
Season with salt, pepper, and lemon juice.
Spread the mixture on a plate to cool.
Divide the mixture into four pieces.
Assemble and bake
Place one portion on each fillet.
Fold over the fillets.
Trim the edges.
Place the fillets in a greased baking dish.
Cover with buttered paper.
Bake at 400°F (200°C) for 10 to 15 minutes.
Serve
Serve on a hot dish.
Coat with white sauce.
Garnish with chopped parsley, sieved yolk, and a sprinkle of pepper.

Flour and butter share little aroma chemistry, yet 124,287 recipes mention both: they likely work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sole
- Forms the delicate fish fillets that wrap the filling and cook gently.
- Lobster
- Adds savoury, sweet shellfish flavour and texture to the filling.
- Flour
- Thickens the butter and stock into a panada that binds the filling.
- Butter
- Adds richness and flavour to the panada and carries the flour.
- Milk or fish stock
- Liquid that hydrates the flour and turns the panada into a smooth, thick base.
- Lemon juice
- Adds acidity that brightens the mild fish and lobster flavours.
The step that matters
Cooling the panada before assembling. A panada must cool and firm up before it is spread and divided. If it is still hot and loose, it will not hold its shape on the fillets and may seep out during baking.
