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 base
Blanch the pickled pork in hot water, drain, and cut into small dice.
Fry the pork in a porcelain-lined kettle until browned.
Add the chopped onion and brown it.
Simmer the chowder
Remove from heat and add the sliced potatoes, salt, pepper, clam juice, and cold water.
Return to heat and boil until the potatoes are tender.
Add the solid clams and mix well.
Thicken and serve
In a separate bowl, mix the milk with the flour until smooth, then add to the chowder.
Bring to a boil, then remove from heat and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pickled fat pork
- Renders fat for frying and adds savory, salty flavor to the base.
- Potatoes
- Provide body and starch that soften and give the chowder its hearty texture.
- Clams
- Supply the main seafood flavor and tender texture to the chowder.
- Flour
- Thickens the milk and broth into a smooth, creamy consistency when brought to a boil.
- Milk
- Adds creaminess and richness, softening the chowder's flavor and texture.
- Onion
- Browning builds sweet, savory depth in the base before liquids are added.
The step that matters
Mixing the flour into the milk. Flour clumps if added dry or unmixed; blending it smoothly into cold milk first lets starch disperse, so it thickens evenly when the chowder boils.
Swap the onion
How well each one fits the dish's main ingredients (pork, potato, pepper, clam, flour, milk):

Fit is the average pairing score against pork, potato, pepper, clam, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
