Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Pilleted Soles a LA Reine
Ingredients
Directions
Prepare the fish
Fillet the sole and cut the fillets into two parts.
Roll up the fillets and tie them with cotton if necessary.
Place the fillets in a stewpan with boiling salted water just to cover and cook for 10 minutes.
Make the sauce
In another stewpan, melt the butter, then add the flour and mix until smooth.
Gradually add hot milk until the sauce reaches a cream-like consistency.
Season the sauce with salt, pepper, and grated horseradish.
Combine and serve
Carefully add the fillets to the sauce, ensuring they are just covered, and simmer for 2 minutes.
Optionally, add chopped parsley before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sole
- Forms the delicate, flaky main body of the dish once cooked.
- Butter
- Enriches the sauce with fat and carries flavour through the roux.
- Flour
- Thickens the butter and milk into a smooth, cream-like sauce.
- Hot milk
- Hydrates the roux and, as it thickens, makes the sauce creamy.
- Grated horseradish
- Adds sharp, pungent heat that cuts through the richness of the sauce.
The step that matters
Adding hot milk to the roux. Adding the milk gradually and keeping it hot lets the starch in the flour swell evenly, giving a smooth sauce without lumps. Cold or rushed milk can cause lumps that are hard to remove.
Swap the parsley
The recipe marks parsley as optional. How well each one fits the dish's main ingredients (butter, flour, milk, cream, pepper, horseradish):
- Nutmegfits better
- Cinnamonfits about as well
- Capersfits about as well
- Parsleythe original
Fit is the average pairing score against butter, flour, milk, cream, pepper, horseradish. Candidates are from the same food group and used in at least 100 recipes.
