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 ↓
Baked Pickerel with Oyster Sauce
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Preheat the oven to 400°F (200°C).
Place the fish on a buttered pan, season with salt and pepper, spread with soft butter, and dredge with flour.
Bake the fish
Bake for 40 minutes, basting with a mixture of butter and water when the flour begins to brown.
Make the oyster sauce
For the oyster sauce, parboil the oysters and drain the liquor.
Add enough milk to the oyster liquor to make 1 cup of sauce.
In a saucepan, cook the butter and corn starch until well mixed, then stir in the milk mixture.
Once smooth, add the cream and oysters, season, and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pickerel
- Forms the main body of the dish, cooking through in the oven to become flaky.
- Flour
- Dredged on the fish, it browns in the oven to add colour and a crisp, golden crust.
- Butter
- Adds richness and moisture to the fish, and thickens the sauce with corn starch as a roux.
- Oysters
- Provide the briny, savoury flavour of the sauce and tender bites of seafood.
- Milk
- Forms the liquid base of the sauce, giving it a smooth, mellow body.
- Corn starch
- Thickens the sauce as it heats, giving it a smooth, glossy consistency.
The step that matters
Stirring the corn starch into the butter before adding the milk. Cooking the butter and corn starch together into a paste lets the starch disperse evenly; adding it straight to liquid can cause lumps that will not smooth out.
