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

What each ingredient does

Cod
Forms the flaky main protein that gently cooks in its own steam.
Mushrooms
Release moisture as they cook, adding savoury depth to the juices in the bag.
Tomatoes
Break down slightly in the heat, adding moisture and gentle acidity to the sauce.
Butter
Adds richness and carries flavour, helping the fish stay moist.
Lemon juice
Adds acidity that brightens the fish and balances the richness of the butter.

The step that matters

Seal the bag. A tight seal traps steam so the fish cooks gently in its own moisture. A leaky bag lets steam escape, which can dry the cod and slow even cooking.

Fit is the average pairing score against pepper, mushroom, tomato, butter, lemon. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
