Why it works: Potato and parsley match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 2,855 recipes mention both. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
The recipe
Ingredients
Directions
Prepare the potatoes
Peel and boil the potatoes until tender.
Drain the potatoes and cut them into slices.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the bulk and starchy body of the dish.
- Thick white sauce or béchamel sauce
- Coats the potatoes with a creamy texture and added moisture.
The step that matters
Toss the potato slices gently. Cooked potato slices are soft and fragile, so rough stirring breaks them apart and leaves the dish mushy instead of neatly coated with sauce.
Flavor stand-ins for the parsley
The recipe marks parsley as optional. How well each one fits the dish's main ingredients (potato, sauce):
- Garlicabout as good a flavor fit
- Capersabout as good a flavor fit
- Parsleythe original
- Dillabout as good a flavor fit
Fit is the average pairing score against potato, sauce. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
