Why it works: Butter and mushroom match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 12,516 recipes mention both. Both carry trans-2-decenal, which smells waxy, orange. The science ↓
The recipe
Ingredients
Contains: milk, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare
Clean the cod and cut it into slices.
Cook
In a stewpan, combine the cod, butter, herbs, mushrooms, and Marsala wine.
Simmer until the mixture is reduced.
Pour in the Neapolitan sauce and cook until the cod is done.
Serve
Remove the cod and arrange it on a dish with a border of macaroni stewed in stock.
Stir the cream with the reduced stock until smooth, then pour over the fish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and helps carry flavour through the simmering liquid.
- Cream
- Adds richness and a smooth, velvety texture to the finished sauce.
- Marsala wine
- Adds acidity and a deep, aromatic sweetness to the reduced liquid.
- Mushrooms
- Add savoury, earthy flavour and a little moisture to the sauce.
The step that matters
Stir the cream into the reduced stock until smooth. Cream added to a very hot, boiling liquid can split and turn grainy. Stirring it in until smooth, with the stock at a gentle heat, helps keep the sauce silky.
