Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
New Potatoes
Ingredients
Directions
Prepare
Wash and scrape the new potatoes, placing them in cold water as you go.
Boil and finish
Put the potatoes in salted boiling water and boil until easily pierced with a fork.
Drain the water and add butter, salt, white pepper, and enough milk to cover the potatoes.
Boil gently for five minutes, then serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- New potatoes
- Provide the starchy base of the dish, cooking to a soft, tender texture.
- Butter
- Adds richness and fat, giving the potatoes a smooth, glossy coating.
- Milk
- Adds moisture and creaminess as it reduces around the potatoes.
The step that matters
Boil until easily pierced with a fork. Potatoes that are undercooked stay firm in the centre, while overcooked ones break apart. Testing with a fork shows when the starch has softened through without the flesh collapsing.
Swap the white pepper
How well each one fits the dish's main ingredients (potato, butter, milk):
- Cinnamonfits better
- Nutmegfits better
- Parsleyfits better
- White pepperthe original
Fit is the average pairing score against potato, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
