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
Layer and simmer
In a soup pot, layer a handful of cod, followed by pork, onion, and pepper, then cover with crackers.
Repeat until all ingredients are used.
Cover with cold water, place the lid on, and simmer gently for about an hour after boiling.
Remove the fish and crackers with a slotted spoon and place them in a tureen set in hot water.
Strain the broth through a colander to remove bones, then return it to the pot.
Thicken and finish
In a small bowl, mix butter and corn-starch, then stir into the broth and bring to a boil.
Add the chopped oysters and parsley, simmer for 5 minutes, then stir in the hot milk.
Pour the chowder into the tureen and serve with hot crackers and sliced lemon.

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, flaking into tender pieces as it simmers in the broth.
- Boston crackers
- Soften in the broth and add body, thickening the chowder as they break down.
- Salt pork
- Adds savory fat and salty flavor that enriches the broth.
- Butter
- Adds richness and, mixed with corn-starch, helps form a smooth thickened base.
- Corn-starch
- Thickens the broth when heated, giving the chowder a smooth, velvety body.
- Oysters
- Contribute briny, delicate seafood flavor and a tender texture when simmered briefly.
The step that matters
Adding the corn-starch mixture to the broth. Corn-starch must be heated to a boil to thicken fully. If it is added lumpy or undissolved, it clumps instead of thickening evenly, leaving the chowder with a pasty texture.
