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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the chowder and contributes its flavor to the broth.
- Potatoes
- Add starch and body, giving the chowder a heartier texture as they cook.
- Milk
- Adds creaminess and mild sweetness to the broth.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the liquid.
- Flour
- Thickens the liquid so it becomes a more substantial, spoonable chowder.
The step that matters
Adding flour to thicken. Flour must be stirred in so it disperses without lumps; starch thickens best when the liquid is hot enough to gelatinize it, so add it gradually while the chowder is simmering.
Swap the potato
How well each one fits the dish's main ingredients (fish, pepper, milk, butter, flour):
- Potatothe original
- Capsicumfits about as well
- Leekfits less well
- Asparagusfits less well
Fit is the average pairing score against fish, pepper, milk, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
