Why it works: Lemon sole and butter work together. They rank in the top 9% of all ingredient pairs, and 29 recipes mention both. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
The recipe
Ingredients
Contains: milk, wheat, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Also mentioned in the method: fish
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
Roll up the filleted soles and tie them with cotton.
Stand the rolled soles in an enamel pie dish.
Bake
Pour the milk, butter, and parsley over the fish.
Cover tightly with another dish that fits.
Bake in a 350°F (175°C) oven for 20 minutes.
Make the sauce and serve
Carefully remove the fish and take out the cotton.
Thicken the remaining liquid with flour and salt.
Serve the fillets standing up with sauce poured over.

Butter and flour share little aroma chemistry, yet 122,858 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
- Lemon soles
- Form the main protein, which turns delicate and flaky when gently baked.
- Milk
- Forms the liquid that gently poaches the fish and becomes the base of the sauce.
- Butter
- Adds fat and richness to the cooking liquid and the finished sauce.
- Flour
- Thickens the remaining cooking liquid into a smooth sauce.
The step that matters
Thicken the remaining liquid with flour and salt. Flour must be cooked in the hot liquid to swell its starch and thicken the sauce; adding it raw or too quickly can leave lumps or a pasty taste.

Fit is the average pairing score against lemon sole, milk, butter, flour. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
