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 ↓
Browned Hash
Ingredients
Directions
Prepare
Combine corned beef, mashed potatoes, boiling water, fat, salt, pepper, onion juice, and parsley in a bowl.
Melt 1 tablespoon of fat in a frying pan over moderate heat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Corned beef
- Provides the savory meat base and most of the hash's characteristic flavor.
- Mashed potatoes
- Bind the hash and add body and moisture to the mixture.
- Fat
- Helps the hash brown in the pan and adds richness.
- Boiling water
- Moistens the mixture so the potatoes and meat hold together evenly.
The step that matters
Cook without stirring. Leaving the mixture undisturbed lets a browned crust form on the bottom, which gives contrast in texture. Stirring breaks up that crust and keeps the hash pale and mushy.
Swap the parsley
How well each one fits the dish's main ingredients (beef, potato, pepper, onion):
- Garlicfits better
- Thymefits about as well
- Parsleythe original
- Celeryfits about as well
Fit is the average pairing score against beef, potato, pepper, onion. Candidates are from the same food group and used in at least 100 recipes.
