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-chouder Soup
Ingredients
Directions
Prepare
Open the clams and chop their flesh.
Make the chowder
In a deep, thickly buttered stewpan, combine the chopped clams, minced onions, diced potatoes, aromatics, salt, pepper, nutmeg, cayenne, and mace.
Moisten with enough wine and fish broth to cover the mixture.
Set the stewpan on a brisk fire and boil for 25 to 30 minutes.
Remove from heat and stir in the bottle of Rhine wine.
Add the bruised crackers or kneaded butter to thicken the soup.
Finish by stirring in the good butter after removing the aromatics.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Clams
- Provide the main flesh and briny flavour that defines the chowder.
- Potatoes
- Release starch as they cook, adding body and texture to the soup.
- Onions
- Add sweetness and savoury depth as they soften into the broth.
- Butter
- Adds richness and a silky mouthfeel to the finished soup.
- Crackers or kneaded butter
- Thicken the soup by absorbing liquid and adding starch.
The step that matters
Stirring in the wine after removing from heat. Alcohol boils off with heat, so adding the wine off the heat keeps more of its aroma and flavour in the finished chowder.
Swap the mace
How well each one fits the dish's main ingredients (clam, onion, potato, pepper, nutmeg, wine, fish):
- Thymefits better
- Parsleyfits better
