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 ↓

Prepare
In a bowl, beat the eggs until well mixed.
Stir the minced ham and chopped onions into the eggs.

Onion and egg barely smell alike, yet cooks put them together in 23,333 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into the structure of the omelette as they cook, holding it together.
- Minced ham
- Adds savory flavor and some fat, which keeps the omelette moist as it cooks.
- Pickling onions
- Add sharp, aromatic flavor that cuts through the richness of the eggs.
The step that matters
Cook until the edges are set, then fold and finish cooking. Eggs set from the edges inward as proteins coagulate with heat. Folding too early can tear the thin, still-liquid center, while cooking too hot browns and toughens the eggs before the middle sets.
Swap the onion
How well each one fits the dish's main ingredients (ham, egg):
- Asparagusfits better
- Mustardfits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against ham, egg. Candidates are from the same food group and used in at least 100 recipes.
