Why it works: Potato and parsley are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 2,855 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Potatoes
Ingredients
Directions
Prepare
Choose new potatoes of similar size, wash, and dry them.
Cook in butter
Melt the butter in a pan over heat until boiling.
Add the potatoes to the boiling butter and toss occasionally until done.
Check doneness with a fork; remove before they lose crispness.
Finish and serve
Sprinkle with salt and garnish with parsley after boiling briefly in the butter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh butter
- Cooks the potatoes in a fat, adding richness and flavour while the butter boils.
- New potatoes
- Form the main body of the dish, cooking through in the hot butter.
The step that matters
Checking doneness with a fork. Potatoes keep cooking after they are removed from heat, and overcooking softens the surface and loses the crisp edges. Testing with a fork lets the cook pull them at the right moment.
Swap the parsley
How well each one fits the dish's main ingredients (butter, potato):
- Parsleythe original
- Thymefits about as well
- Garlicfits less well
- Nutmegfits less well
Fit is the average pairing score against butter, potato. Candidates are from the same food group and used in at least 100 recipes.
