Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Fish Turbot
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the sauce
Scald the milk, butter, mashed potatoes, and flour in a saucepan until thickened.
Assemble and bake
In a baking dish, layer the fish and the thickened mixture alternately until the dish is filled.
Season each layer with salt and pepper to taste.
Cover the top with cracker crumbs and dot with butter.
Bake at 350°F (175°C) for 30 minutes.

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
- Milk
- Forms the liquid base of the thickened sauce that moistens the fish.
- Flour
- Thickens the scalded milk mixture into a smooth, cohesive sauce.
- Butter
- Adds richness and fat that carries flavour and helps the top brown.
- Mashed potatoes
- Adds body and starch to the sauce, helping it hold together and stay moist.
- Eggs
- Not used in any step of the method, so no role is stated.
The step that matters
Scalding and thickening the sauce. Milk scorches easily on the bottom of a saucepan, and flour must be heated fully to thicken properly. Stirring constantly over gentle heat keeps the sauce smooth and prevents lumps.
Swap the potato
How well each one fits the dish's main ingredients (milk, butter, flour, egg, whitefish, pepper):
- Potatothe original
- Capsicumfits about as well
- Chivefits about as well
- Shallotfits less well
Fit is the average pairing score against milk, butter, flour, egg, whitefish, pepper. Candidates are from the same food group and used in at least 100 recipes.
“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.
