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 ↓
Corn Chowder
Ingredients
Directions
Make the base

Add the corn, diced potato, and boiling water. Cook for 30 minutes.
Make the milk mixture
In a separate pan, melt the butter and stir in the flour to make a roux.

Finish and serve
Stir in the salt, Tabasco sauce, and rolled crackers before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potato
- Breaks down partly as it cooks, adding body and thickening the chowder.
- Flour
- Thickens the milk with the butter, giving the chowder a smooth, creamy body.
- Milk
- Forms the creamy base that gives the chowder its richness and mild sweetness.
- Ham
- Adds savory, salty flavor and aroma from the start of the cooking.
- Crackers
- Soak up liquid and further thicken the chowder as they are stirred in.
The step that matters
Gradually add the hot milk to the roux, stirring until smooth. Adding milk slowly while stirring lets the flour disperse evenly in the fat and liquid. Dumping it in at once makes lumps that are hard to smooth out later, and the starch only thickens properly when it is evenly distributed.
