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 ↓
Oyster Chowder
Ingredients
Directions
Prepare
Wash the oysters, pick over, drain, and boil the oyster liquor; skim off any impurities.
Make the chowder
Fry the salt pork pieces until crispy, then add the chopped onion and fry until yellow.
Remove the pork and onion scraps, then add the parboiled potatoes to the pot.
Cover the potatoes with boiling water and cook until tender.
Add the oyster liquor and oysters, cooking until the edges of the oysters curl.
Mix the flour with a little cold water to make a thin paste.
Add the paste to the chowder and cook for five minutes.
Stir in the hot milk, butter, and season with salt and pepper.
Serve
Add a few oyster crackers and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main flavour and texture; they firm and curl when cooked through.
- Potatoes
- Add body and starch that make the chowder hearty and thicken it slightly.
- Flour
- Thickens the broth into a smooth, creamy consistency when cooked.
- Milk
- Adds richness and a creamy texture to the chowder.
- Salt pork
- Renders fat that carries flavour through the pot and adds savoury depth.
- Onion
- Adds sweetness and aromatic depth as it softens in the rendered fat.
The step that matters
Adding the flour paste. Flour must be mixed smooth with cold water first and then cooked for several minutes; added dry or lumpy, it forms clumps and leaves a raw floury taste.
