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 ↓
Creamed Potatoes
Ingredients
Directions
Wash, peel, and cut the potatoes into small cubes.
Place the potatoes in a frying pan with finely chopped onion and parboil for 10 minutes.
Pour off the water, then add butter, salt, pepper, and enough milk to cover the potatoes.
Cook for 15 to 20 minutes, stirring frequently, until the potatoes are tender and the sauce is thick and creamy.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the dish and, as they cook, release starch that thickens the milk into a creamy sauce.
- Milk
- Provides the liquid that cooks down with the potato starch into a creamy sauce.
- Butter
- Adds richness and a smooth mouthfeel to the creamy sauce.
- Onion
- Adds aromatic flavour to the potatoes and milk as they cook.
The step that matters
Cook for 15 to 20 minutes, stirring frequently. Milk can scorch on the bottom of the pan as it reduces. Frequent stirring keeps the heat even and prevents sticking, while the potato starch thickens the liquid into a smooth sauce.
