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 ↓
Oyster Chowder
Ingredients
Directions
Prepare
Drain the oysters and remove any shell particles by running them through your fingers.
Strain the oyster liquor through a fine wire sieve.
Thinly slice the potatoes and onion, then boil them gently in the oyster liquor until tender.
Make the chowder
Wet the flour with a little milk and stir it into the scalding milk heated in a double boiler, adding the butter, salt, and pepper.
Cook for about a minute, then add the oysters and boil for two minutes.
Combine the potatoes, onion, and their cooking liquor with the milk mixture.
Serve
Place the crackers or sea biscuits in a tureen, pour the chowder over them, and serve immediately.

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, cooked briefly so they stay tender.
- Potatoes
- Add body and starch that thickens the chowder and make it hearty.
- Milk
- Forms the creamy base that carries the other ingredients.
- Pilot or sea biscuits
- Soak up the broth and give the chowder a thick, bready body when served.
- Flour
- Thickens the milk into a smooth, lightly bodied base.
- Butter
- Adds richness and a rounded, savoury flavour to the base.
The step that matters
Stirring the flour into the scalding milk. Flour lumps if added dry or without being wetted first, and lumps won't dissolve evenly. Wetting it with a little milk into a smooth paste lets the starch disperse and thicken the milk evenly.
Swap the onion
How well each one fits the dish's main ingredients (oyster, potato, milk, biscuit, flour, butter, pepper):
- Chivefits better
- Asparagusfits better
