Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Sole with Cream Sauce
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
Wash, skin, and fillet the sole, then cut each fillet lengthwise into two strips.
Tie each strip loosely into a knot or fold the ends over each other.
Place the fish on a greased baking tray.
Season the fish with salt and pepper.
Sprinkle the fish with lemon juice.
Cover the fish with greased paper.
Bake at 350°F (175°C) for 10 to 15 minutes.
Make the sauce
Simmer the fish bones, onion, and mace in the milk for about 15 minutes.
Strain the stock.
Season the stock to taste.
Melt the butter in a saucepan.
Add the flour and cook for 3 to 4 minutes.
Pour in the milk and stir until it boils.
Let the sauce simmer for at least 10 minutes.
Serve
Arrange the fish on a hot dish, either in a circle or in two rows.
Strain the sauce over the fish evenly.
Decorate with chopped parsley or lobster coral.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they 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 main body of the dish, cooking into tender, flaky fillets.
- Butter
- Enriches the sauce and carries flavour while melting with the flour.
- Flour
- Thickens the milk into a smooth sauce when cooked briefly with the butter.
- Milk
- Forms the liquid base of the sauce, becoming creamy as it thickens.
The step that matters
Add the flour and cook for 3 to 4 minutes. Cooking the butter and flour together, a roux, removes the raw starchy taste and lets the flour thicken smoothly. Skipping this time leaves a pasty flavour and lumps when the milk is added.
Swap the mace
How well each one fits the dish's main ingredients (milk, butter, flour, onion, lemon, pepper):
- Parsleyfits better
- Thymefits better
- Cardamomfits better
- Macethe original
Fit is the average pairing score against milk, butter, flour, onion, lemon, pepper. Candidates are from the same food group and used in at least 100 recipes.
