Why it works: Potato and milk are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 3,611 recipes. Both carry (e,z)-2,6-nonadienal, which smells cucumber, melon. The science ↓
Potatoes
Ingredients
Directions
Prepare
Wash the potatoes thoroughly and ensure they are of even size.
Cook
Drop the potatoes into boiling water and cook until a fork pierces them with slight resistance.
Pour off the water.
Place the pot back on the heat, removing the cover to let the steam escape.
Serve
Serve the potatoes hot, without removing the skins.
Optionally, pour a dressing of hot milk mixed with a thin batter over the potatoes before serving.

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Milk and flour barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the main body of the dish, with a starchy, fluffy interior when cooked through.
- Milk
- Adds richness and a creamy, smooth texture to the optional dressing.
- Flour
- Thickens the milk into a light batter-based dressing, giving it body.
The step that matters
Place the pot back on the heat to dry the potatoes. Returning the drained potatoes to low heat lets surface moisture evaporate, so they taste less watery and hold together better. Removing the cover lets the steam escape instead of condensing back onto them.
Swap the potato
How well each one fits the dish's main ingredients (milk, flour):
- Arrowrootfits better
- Potatothe original
- Sweet potatofits about as well
- Parsnipfits about as well
Fit is the average pairing score against milk, flour. Candidates are from the same food group and used in at least 100 recipes.
