Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Cod Chowder
Ingredients
Directions
Prepare the layers
Cut the cod into dice.
Layer a double handful of cod in the bottom of a soup pot.
Add sliced pork, onion, and pepper, then cover with crackers.
Repeat layering until all ingredients are used.
Stew
Cover with cold water and put on the pot lid.
Stew gently until the fish is tender, about 1 hour after boiling begins.
Strain and serve
Remove fish and crackers with a slotted spoon and place in a tureen.
Strain the broth through a colander to remove bones, then return to the kettle.
Heat the broth before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod fish
- Forms the main body of the chowder and becomes tender during slow stewing.
- Boston crackers
- Soak up cooking liquid and thicken the chowder while adding body.
- Salt pork
- Adds fat and savory flavor that seasons the broth as it cooks.
- Oysters
- Contribute briny flavor and a soft, rich texture to the chowder.
- Milk
- Adds creaminess and mild sweetness to the broth.
The step that matters
Stew gently until the fish is tender. Boiling vigorously toughens and breaks up delicate fish flesh, while gentle simmering cooks it evenly and keeps the pieces intact.
