Why it works: Beef and potato are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 2,052 recipes. Both carry sotolon, which smells curry, maple. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold beef
- Provides the main meaty body and flavor of the hash.
- Mashed potatoes
- Binds the chopped beef together and adds moisture and body to the mixture.
- Butter
- Browns the slices, adding fat and a rich, toasted flavor to the surface.
The step that matters
Browning the slices in butter. The surface needs enough heat and fat to brown rather than steam. Browning, driven by the Maillard reaction between proteins and sugars, creates the savory crust and deeper flavor that define a good hash.
Swap the potato
How well each one fits the dish's main ingredients (beef, butter):
- Potatothe original
- Onionfits about as well
- Chivefits less well
- Tomatofits less well
Fit is the average pairing score against beef, butter. Candidates are from the same food group and used in at least 100 recipes.
