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 Potato
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Cook the potatoes
Boil the diced potatoes until tender, then drain.
Make the cream sauce
In a saucepan, melt the butter over medium heat.
Stir in the flour and cook for 1 minute.
Gradually add the milk, stirring constantly until thickened.
Combine and serve
Add the cooked potatoes, onion, and molasses, mixing well.
Serve hot with salt pork.

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 give it a soft, starchy body.
- Flour
- Thickens the butter and milk into a smooth, stable cream sauce.
- Butter
- Carries flavor and enriches the sauce, adding richness to the cream.
- Milk
- Forms the liquid base of the sauce, adding moisture and creaminess.
- Molasses
- Adds sweetness and a deep, dark flavor to the finished dish.
The step that matters
Gradually add the milk, stirring constantly until thickened. Adding liquid all at once to a flour and butter roux forms lumps, because the starch granules clump before they can disperse. Adding it slowly while stirring lets the starch hydrate evenly, producing a smooth sauce that thickens as it heats.
Swap the onion

Fit is the average pairing score against potato, butter, flour, milk, molasses, pork. Candidates are from the same food group and used in at least 100 recipes.
