Why it works: Ham and egg are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 4,526 recipes. Both carry 2,4-decadienal, which smells seaweed. 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 soft starch that holds the hash together while frying.
- Boiled ham
- Supplies the savory, salty flavor and firm meaty bite of the hash.
- Eggs
- Bind the potato and ham mixture so it holds its shape and sets when fried.
The step that matters
Frying the flat cake until golden brown. The egg binder sets as it heats, and the surface browns through the Maillard reaction. Cooking it too gently leaves the cake soft and crumbly, while high heat can scorch the outside before the centre is hot and firm.
Swap the potato
How well each one fits the dish's main ingredients (ham, egg):

- Potatothe original
Fit is the average pairing score against ham, egg. Candidates are from the same food group and used in at least 100 recipes.
