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 ↓
To Fricassee Cod Sounds and Tongues
Ingredients
Directions
Prepare the cod
Soak the cod tongues in fresh water overnight.
Remove the skins and cut them into two pieces.
Boil the pieces in a mixture of milk and water until tender.
Drain in a colander and season with nutmeg, pepper, and a little coarse sea salt.
Make the sauce
In a separate bowl, mix a good lump of butter with flour.
Melt the butter‑flour mixture in the milk to create a sauce.
Combine the sauce with the cod tongues.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod sounds and tongues
- Form the main body of the dish, giving it a tender, flaky bite once cooked.
- Butter
- Adds richness and fat, and with flour forms the base that thickens the sauce.
- Flour
- Thickens the sauce when cooked with butter and milk, giving it body.
- Milk
- Forms the liquid of the sauce and adds creamy richness.
The step that matters
Melt the butter-flour mixture in the milk to create a sauce. Flour needs to be cooked in the hot liquid so its starch swells and thickens evenly; adding it in lumps or without enough heating leaves a pasty, raw-tasting sauce.
Swap the nutmeg
How well each one fits the dish's main ingredients (milk, pepper, butter, flour):
- Cinnamonfits about as well
- Nutmegthe original
- Cardamomfits about as well
- Parsleyfits about as well
Fit is the average pairing score against milk, pepper, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
