Why it works: Pepper and parsley 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the body of the dish, turning crisp on the outside while staying soft inside.
- Butter
- Adds fat for frying, helping the potatoes brown and carrying flavor.
- Fat
- Raises the frying temperature and helps the potatoes brown evenly without burning.
The step that matters
Browning the bottom before folding. The potatoes must form a firm, golden crust on the bottom before folding. If they are stirred or moved too early, the crust will not form and the cake will break apart.
Swap the potato
How well each one fits the dish's main ingredients (pepper, parsley, butter):
- Carrotfits better
- Shallotfits about as well
- Potatothe original
- Capsicumfits about as well
Fit is the average pairing score against pepper, parsley, butter. Candidates are from the same food group and used in at least 100 recipes.
