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 ↓
Steamed Fish with Sauce
Ingredients
Directions
Prepare the fish
Fillet and skin the fish.
Lay the fillets on a buttered plate and cover with another plate.
Steam and make the sauce
Set the plate over a pan of boiling water and cook for 5 to 15 minutes, until the fillets are white and firm.
Break up the bones and skin, place them in a pan, and add the milk; simmer for 10 minutes.
Melt the butter in a separate pan, add the flour, and stir until smooth.
Add enough liquid from the bones to create a thick sauce, then stir in the lemon juice, Liebig Extract of Meat, and salt.
Finish and serve
Boil gently for 2 to 3 minutes, strain over the fillets, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sole or small plaice
- Forms the delicate white fillets that are steamed until firm and flaky.
- Milk
- Liquid base that, with the fish bones, forms the body of the sauce.
- Butter
- Fat that melts with the flour to start the roux for the sauce.
- Flour
- Thickens the sauce when cooked with the melted butter.
The step that matters
Adding the bone liquid to the roux. Liquid added to a flour and butter mixture should be added gradually while stirring. This keeps the sauce smooth and lump-free, and lets it thicken evenly as the starch swells in the heat.
Swap the lemon
