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 ↓
Crimp Cod
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the cod
Wash the cod fillets thoroughly.
Soak them in warm water for 30 minutes, then scrape and clean.
Boil the fillets in milk and water until tender, but not too soft.
Make and roll the fillets
Let them cool, then prepare a forcemeat with chopped oysters, breadcrumbs, butter, nutmeg, pepper, salt, and egg yolks.
Spread the forcemeat thinly over the fillets and roll them up like chickens, securing with skewers.
Roast and serve
Dust with flour and roast in a 300°F (150°C) oven until cooked through.
Serve with oyster sauce.

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
- Cod
- Forms the main body of the dish, becoming flaky and tender when gently cooked.
- Egg yolks
- Bind the forcemeat and help it set as it cooks.
- Butter
- Adds fat for richness and a softer, moister texture in the filling.
- Milk
- Poaching liquid that keeps the fish tender and adds a mild creaminess.
- Flour
- Dusted on the outside to help the surface brown in the oven.
The step that matters
Boil the fillets until tender, but not too soft. Cod flakes apart easily once overcooked, and the fillets are cooked again in the oven, so stopping at tender keeps them intact when rolled and roasted.
Swap the nutmeg
How well each one fits the dish's main ingredients (milk, butter, pepper, egg, flour, oyster, sauce):
- Nutmegthe original
- Capersfits about as well
- Parsleyfits about as well
- Tarragonfits less well
Fit is the average pairing score against milk, butter, pepper, egg, flour, oyster, sauce. Candidates are from the same food group and used in at least 100 recipes.
