Why it works: Butter and milk 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 ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the pastry
Roll out two circles of puff pastry and cut them out.
Mark one circle with a smaller cutter, leaving a 1-inch margin.
Wet the edges of the uncut circle and place the marked circle on top, pressing lightly.
Bake in a 400°F (200°C) oven until cooked, then remove the inner circle to create a lid.
Make the fish balls
Mince and pound the fish or lobster, then mix with cream, salt, cayenne, and egg yolks until smooth.
Shape the mixture into small balls with floured hands.
Make the sauce and serve
Melt butter in a pan, add flour, and stir without coloring.
Gradually pour in milk or fish stock, stirring continuously until it boils.
Add mace, bouquet garni, onion, salt, and pepper, and simmer for 15 minutes.
Add the fish in flakes and 1 oz of butter, cover with buttered paper and the pan lid, and cook gently for 20 minutes.
Remove the bouquet, mace, and onion before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White fish or lobster
- Forms the main body of the filling, giving it its flaked, delicate texture.
- Egg yolks
- Bind the fish mixture and set during cooking to give it a smooth, firm texture.
- Thick cream
- Adds moisture and richness, keeping the fish mixture soft and smooth.
- Butter
- Adds fat and flavour to the sauce and enriches the finished dish.
- Flour
- Thickens the milk or stock into a smooth sauce with butter.
The step that matters
Stir the roux without coloring. Flour cooked in butter must be stirred gently and kept pale so it thickens smoothly and without a toasted taste. Adding liquid gradually while stirring prevents lumps.
Swap the mace
How well each one fits the dish's main ingredients (cream, fish, egg, butter, flour, milk, onion):
- Nutmegfits better
- Capersfits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against cream, fish, egg, butter, flour, milk, onion. 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.
