Why it works: Butter and milk 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 ↓
Cod Chowder
Ingredients
Directions
Prepare and layer
Cut the cod into dice.
In a soup pot, layer a double handful of cod, followed by pork, sliced onion, and pepper.
Cover with crackers and repeat the layering until all ingredients are used.
Simmer and serve
Cover with cold water, place the lid on the pot, and simmer gently until the fish is tender, about 1 hour after boiling begins.
Remove the fish and crackers with a slotted spoon and place them in a tureen, keeping it warm in hot water.
Strain the broth through a colander to remove bones, then return it to the kettle and heat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod
- Forms the main body of the chowder, becoming tender and flaky during gentle simmering.
- Boston crackers
- Soak up cooking liquid and help thicken the chowder while adding body.
- Salt pork
- Adds fat and savory flavor that carries through the broth.
- Corn-starch
- Thickens the broth, giving it a smoother, more body-filled texture.
- Oysters
- Contribute briny, savory flavor and a tender texture to the chowder.
- Milk
- Adds creaminess and mild sweetness, softening the chowder's body.
The step that matters
Simmering the fish gently. Keeping the liquid at a gentle simmer cooks the cod until tender without breaking it into shreds. A hard boil toughens the proteins and fragments the flakes.
