Why it works: Milk and butter 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 ↓
To Cook Small New Potatoes
Ingredients
Directions
Prepare the potatoes
Soak the small new potatoes in cold water for 1 hour.
Rub off the skin with a coarse cloth.
Boil the potatoes until tender, then drain well.
Make the cream sauce
Add enough milk to nearly cover the potatoes and heat it to boiling.
In a separate bowl, cream together the butter and flour, then stir into the hot milk.
Stir well to prevent the potatoes from sticking, being careful not to break them.
Season with salt and pepper, and add more butter if desired.
Serve hot in a deep dish.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Small new potatoes
- Provide the starchy base that softens into tender pieces in the milky sauce.
- Milk
- Forms the creamy liquid that coats the potatoes and makes the sauce.
- Butter
- Adds richness and fat, giving the sauce a smooth, silky mouthfeel.
- Flour
- Thickens the milk into a creamy sauce when cooked with the butter and hot liquid.
The step that matters
Stir the flour and butter into the hot milk. Flour mixed with butter and added to boiling milk can clump if not stirred well. Stirring disperses the starch so the sauce thickens smoothly rather than lumpy.
Swap the potato
How well each one fits the dish's main ingredients (milk, butter, flour, pepper):
- Potatothe original
- Capsicumfits about as well
- Chivefits less well
- Shallotfits less well
Fit is the average pairing score against milk, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
