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
In a pan, fry the diced pickled pork and chopped onions in butter until thoroughly cooked.
Add the flour and brown well, then set aside on the back of the stove.
Make the chowder
In a separate pot, bring the clams in their liquor to a boil for 3 minutes, then strain and return the liquor to the heat.
Add the fried pork and onions, milk, cream, diced potatoes, and salt to the clam liquor.
Just before serving, stir in the chopped clams, toasted bread, and thyme.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pickled pork
- Adds salty, smoky fat that flavours the broth as it renders in the pan.
- Flour
- Browned with the fat, it thickens the chowder base and gives it body.
- Clams
- Provide the main seafood flavour, and their liquor adds savoury depth to the broth.
- Milk
- Forms the creamy liquid that gives the chowder its smooth, mild body.
- Potatoes
- Add starch and soft texture that make the chowder more substantial.
- Toasted bread
- Soaks up broth and adds a toasty texture and aroma when stirred in at the end.
The step that matters
Browning the flour. Flour must be cooked in the fat until well browned so it loses its raw starchy taste and thickens smoothly. Adding it too pale or leaving it to clump can leave the chowder tasting raw or lumpy.
Swap the onion
