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 ↓
Hashed Brown Potatoes
Ingredients
Directions
Prepare the potatoes

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the hash and soften into a tender, starchy base.
- Cream
- Adds moisture and richness, keeping the potatoes soft and creamy as they stew.
- Butter
- Adds fat and flavor, and helps the top brown richly under the broiler.
The step that matters
Browning the top under the broiler. Broiling heat browns the surface quickly, and the sugars and milk solids in the cream and butter can scorch within moments. Watch closely and pull the dish as soon as the top is golden.
Swap the onion
How well each one fits the dish's main ingredients (potato, cream, butter, pepper, parsley):
- Carrotfits better
- Chivefits about as well
- Spinachfits about as well
- Onionthe original
Fit is the average pairing score against potato, cream, butter, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
