Why it works: Pepper and lemon 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 ↓
Filets De Sole a LA Cardinal
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 fish
Skin the soles and fillet them by slipping a knife down the back from head to tail.
Lift the fillets carefully from the bones.
Sprinkle both sides of the fillets with salt, pepper, and lemon juice.
Fold the fillets in half.
Lay the folded fillets in a buttered baking dish.
Cover the fillets with buttered paper.
Make the sauce
In a pan, combine the bones, parsley, mace, onion, celery, and broken bay leaf with 1¼ cups of water or stock.
Simmer the mixture slowly for 15 minutes.
Melt the butter in another pan.
Stir in the flour, seasonings, and lemon juice.
Strain the stock from the bones into the flour mixture.
Add cream to the mixture.
Boil the sauce for 3 minutes.
Bake and serve
Bake at 400°F (200°C) for 15 to 20 minutes.
Lift the fish out of the baking dish to drain.
Brush the fish with the sauce.
Sprinkle the fish with finely minced parsley and lobster coral.
Arrange the fillets on a serving dish, allowing each to rest against the other.
Strain the sauce around the fillets.
Serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soles
- Provide the delicate white fish flesh that is filleted, folded and baked.
- Cream
- Adds richness and body to the sauce, giving it a smooth, silky texture.
- Flour
- Thickens the butter-based sauce so it coats the fish.
- Butter
- Enriches the sauce with fat and carries flavour from the cooking base.
- Fish stock
- Forms the liquid base of the sauce, made from the fish bones and aromatics.
- Lobster coral
- Adds colour and a rich, briny flavour to the finished garnish.
The step that matters
Boil the sauce for 3 minutes. Flour needs sustained heat to cook out its raw starch taste and to thicken fully. Boiling too briefly leaves the sauce floury, while the cream should be added before boiling to avoid curdling in excess heat.
Swap the mace
How well each one fits the dish's main ingredients (pepper, cream, lemon, fish, flour, butter, onion):
- Parsleyfits better
- Tarragonfits better
- Capersfits better
- Macethe original
Fit is the average pairing score against pepper, cream, lemon, fish, flour, butter, onion. Candidates are from the same food group and used in at least 100 recipes.
