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 ↓
Clam Chowder
Ingredients
Directions
Prepare the clams
Boil the clams in water, then remove from the shells.
Strain the clam liquor.
Make the chowder
Fry the salt pork and chopped onion until brown and crisp.
Cook the sliced potatoes in water until tender.
Add the clam liquor, pork scraps, and onion to the potatoes.
Melt the butter in a pan. Stir in the flour. Mix with some of the hot clam liquor.
Combine this mixture with the chowder and add the clams.
Stir in the rich milk and serve with crackers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Clams
- Provide the main flavour and texture of the chowder, and their liquor adds savoury depth.
- Salt pork
- Renders fat and leaves crisp, browned bits that add savoury flavour.
- Potatoes
- Soften during cooking and thicken the chowder while adding body.
- Butter
- Adds richness and carries flavour, and with flour forms the thickening base.
- Flour
- Thickens the chowder when cooked with butter and clam liquor.
- Rich milk
- Adds creaminess and richness to the finished chowder.
The step that matters
Mixing the flour with butter and hot clam liquor. Flour must be cooked in butter and blended with hot liquid carefully, or it clumps instead of thickening the chowder smoothly.
