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 ↓
Potato Chowder
Ingredients
Directions
Fry the base
Fry the salt pork and onions together until both are a delicate brown.
Layer and simmer
In a kettle, layer sliced potatoes, then onions and pork, sprinkling with salt between layers.
Pour the grease from the frying pan over the layers and add the water.
Cover and simmer for 20 minutes, or until the potatoes are tender.
Thicken and serve
Thicken the milk with the flour mixed with the butter, then pour it over the potatoes.
Stir carefully to avoid breaking the potatoes.
Serve very hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the main body of the chowder and release starch that lightly thickens the broth.
- Salt pork
- Renders fat and savory flavor into the grease that cooks the layers.
- Milk
- Adds creaminess and liquid richness to the finished chowder.
- Flour
- Its starch thickens the milk when heated, giving the chowder a fuller texture.
- Butter
- Adds fat and richness, and mixing it with flour helps the flour blend smoothly.
- Onion
- Browning adds sweetness and aroma to the frying base.
The step that matters
Thickening the milk with flour and butter. Flour clumps if added straight to hot liquid. Mixing it with butter first coats the starch granules so they disperse evenly. Heating the mixture then gelatinizes the starch and thickens the milk smoothly.
