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
Prepare
Soak the clams in fresh water for 3-4 hours to remove sand.
Steam the clams as directed for canning.
Remove the meat from the shells and run it through a sausage mill.
Mix the clam meat with potatoes, onion, turnip, and beef.
Fill and seal
Fill one-pound cans three-fourths full with the mixture.
Strain the juice from the bottom of the tank and fill the cans to within ¼ inch of the top.
Seal the cans, leaving a small hole at the top.
Process and cool
Place the cans in boiling water for 20 minutes.
Remove the cans, seal the hole, and cook in boiling water for 1.5 hours.
Cool the cans in cold water.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Clams
- Provide the main seafood flavor and the chunky, tender texture of the chowder.
- Potatoes
- Supply starch that gives the chowder body and a soft, creamy texture as they cook.
- Onion
- Adds aroma and mild sweetness as it softens during cooking.
- Turnip
- Adds mild sweetness and extra body to the mixture.
- Beef
- Contributes savory, meaty depth to the broth.
The step that matters
Leaving the small hole before the long boil. The vent lets steam and trapped air escape during the first heating. Sealing it before the 1.5-hour boil keeps the can closed while the contents reach full cooking temperature, so the seal forms properly and the chowder stays safely preserved.
Swap the turnip
How well each one fits the dish's main ingredients (clam, potato, onion, beef):
- Chivefits better
- Tomatofits better
- Carrotfits better
- Turnipthe original
Fit is the average pairing score against clam, potato, onion, beef. Candidates are from the same food group and used in at least 100 recipes.
