Why it works: Onion and potato are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
Prepare the base
Fry the salt pork in a pan until dry, then remove the scraps.
Cook the onion in the fat until soft.
Sear the fish
Season the fish with salt and pepper, then coat with flour.
Sear the fish in the hot fat until browned, then cover and reduce heat to cook slowly.
Simmer and finish
Parboil the potatoes for 10 minutes, then drain.
Add the potatoes and fish broth to the pan with the fish.
Simmer gently for about 30 minutes until well done.
Stir in the butter, milk, and broken crackers before serving.

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, becoming tender and flaky as it simmers.
- Potatoes
- Soften during simmering and thicken the chowder while adding body.
- All-purpose flour
- Coats the fish and helps brown it, and thickens the liquid slightly.
- Salt pork
- Renders fat for frying and adds savory, smoky flavor to the base.
- Milk
- Adds richness and creaminess to the finished broth.
- Crackers
- Soak up liquid and thicken the chowder while adding body.
The step that matters
Sear the fish in the hot fat until browned. Searing the floured fish in hot fat browns its surface and builds flavor. Covering and lowering the heat afterward then cooks it gently, which helps keep the flesh from breaking apart.
