Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Cod
Forms the main flesh of the dish, cooked gently in butter until flaky.
Baked flour
Dredging coat and batter base that helps the surface brown and crisp when fried.
Egg
Binds the batter so it clings to the oysters during frying.
Milk
Liquid in the batter that helps form a smooth coating.
Oysters
Main shellfish, coated in batter and fried until the coating sets.
Butter
Frying fat that carries heat to the fish and adds browning and rich flavour.

The step that matters

Frying the cod over low heat. Cod is lean and delicate, so gentle heat cooks it through evenly and keeps it moist. Too much heat can dry the outside before the centre is done, and the floured coating can scorch in the butter.

Swap the shallot

The recipe marks shallot as optional. How well each one fits the dish's main ingredients (vinegar, flour, butter, milk, egg, oyster, lemon):

  1. Shallotthe original
  2. Asparagusfits about as well
  3. Cucumberfits less well
  4. Chivefits less well

Fit is the average pairing score against vinegar, flour, butter, milk, egg, oyster, lemon. Candidates are from the same food group and used in at least 100 recipes.
