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 ↓

Moisten the mixture with about ½ cup of stock, adding more if the potatoes are dry.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Corned beef
- Provides the main meaty flavour and savoury body of the hash.
- Mashed potatoes
- Bind the mixture and give it a soft, moist texture.
- Butter or dripping
- Adds fat for frying and helps the hash brown on the pan surface.
- Stock
- Adds moisture and savoury flavour to the potato and beef mixture.
The step that matters
Cooking until browned. Frying the mixture undisturbed in a hot pan lets the surface brown through the Maillard reaction, which adds rich flavour and crispness. Stirring too often or using a cool pan leaves it pale and soggy.
Swap the parsley
How well each one fits the dish's main ingredients (beef, potato, butter, pepper, bread):
- Parsleythe original
- Thymefits about as well
- Marjoramfits less well
- Garlicfits less well
Fit is the average pairing score against beef, potato, butter, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
