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 liquor from the oysters.
Cook the liquor with the grated onion and sliced potatoes until tender.
In a separate bowl, rub together the butter and flour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oysters
- Provide the main flavor and tender texture, plumping when briefly heated in the chowder.
- Potatoes
- Add body and starch that soften during cooking and give the chowder substance.
- Milk
- Forms the creamy base of the chowder, giving it richness and smooth texture.
- Flour
- Combined with butter, it thickens the milk so the chowder becomes creamy rather than watery.
- Butter
- Adds fat and richness, and carries flour into the milk for thickening.
- Grated onion
- Adds aromatic flavor to the oyster liquor as it cooks with the potatoes.
The step that matters
Adding the butter and flour mixture to the milk. Flour thickens only when heated in fat and liquid, and it can clump if added raw. Mixing it into butter first and adding it to boiling milk helps it disperse smoothly and thicken evenly.
