Why it works: Potato and onion 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 ↓
Clam Chowder
Ingredients
Directions
Make the chowder
Place the salt pork in the bottom of a soup kettle and cook until the fat is rendered.
Add boiling water, sliced potatoes, sliced onion, and chopped clams to the kettle.
Boil for 25 minutes, then season with salt and pepper.
Add scalded milk and butter to the mixture.
Finish and serve
Break the crackers in half and place them on top of the chowder.
When the crackers are soft, the chowder is ready to serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt pork
- Renders fat that carries flavour into the broth as the base of the chowder.
- Potatoes
- Soften during boiling and thicken the chowder body with their starch.
- Milk
- Adds creaminess and mild sweetness to the broth.
- Butter
- Adds richness and a silky mouthfeel to the finished chowder.
- Crackers
- Soak up broth and soften on top, adding body to the chowder.
The step that matters
Adding the scalded milk. Hot milk added to a boiling chowder can curdle or scorch, so it should be scalded first and added while the mixture is kept at a gentle heat.
Swap the onion
