Why it works: Potato and butter are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 6,456 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Provides the bulk and starch that hold the hash together.
- Chopped ham
- Adds savory flavor and salty, meaty character to the cake.
- Eggs
- Bind the potatoes and ham so the mixture sets into a cohesive cake.
The step that matters
Cook until golden brown on both sides. Browning develops flavor through the Maillard reaction, but a large flat cake needs enough fat and steady medium heat to brown evenly without burning. Pressing it gently lets the surface contact the pan, and flipping only once keeps the cake intact.
Swap the potato
How well each one fits the dish's main ingredients (ham, egg, butter):
- Asparagusfits better
- Leekfits about as well
- Chivefits about as well
- Potatothe original
Fit is the average pairing score against ham, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
