Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
New Potatoes and Cream
Ingredients
Directions
Prepare the potatoes
Wash and scrub the new potatoes with a coarse cloth or scrubbing brush.
Drop the potatoes into boiling water and boil until tender.
Press a potato against the side of the kettle with a fork; if it yields to gentle pressure, it's done.
Make the cream sauce
In a saucepan, heat butter and cream until hot but not boiling.
Add chopped parsley, pepper, and salt to the butter and cream mixture.
Combine and serve
Drain the potatoes, add the butter and cream mixture, and place over hot water for 1-2 minutes.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- New potatoes
- Form the bulk of the dish, with a tender, starchy interior that soaks up the sauce.
- Butter
- Adds richness and a smooth, rounded flavour to the sauce.
- Cream
- Adds body and a silky texture that coats the potatoes.
The step that matters
Heating the butter and cream. Heating only until hot, not boiling, keeps the cream from scorching or splitting, so the sauce stays smooth and coats the potatoes evenly.
Swap the potato
How well each one fits the dish's main ingredients (butter, cream, parsley, pepper):
- Potatothe original
- Carrotfits about as well
- Spinachfits about as well
- Shallotfits less well
Fit is the average pairing score against butter, cream, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
