Why it works: Egg and butter are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 118,967 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Plain Omelette
Ingredients
Directions
Prepare
Beat the eggs until very light.
Add salt, pepper, and hot water to the eggs.
Cook
Heat the omelette pan and add bacon fat or butter.
Cook slowly until thickened and browned underneath.
Place in the oven to finish cooking the top.
When the top does not stick to your finger, the omelette is done.
Serve
Fold the omelette and serve on a hot platter.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Egg and pepper barely smell alike, yet cooks put them together in 50,580 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
- Provide the protein that sets into the omelette's structure as it cooks.
- Bacon fat or butter
- Adds fat for flavor and helps keep the omelette from sticking and encourages browning.
- Hot water
- Adds moisture that turns to steam, keeping the omelette more tender.
The step that matters
Cook slowly until thickened and browned underneath. Gentle heat lets the egg proteins set evenly without tightening and toughening. Too much heat sets the bottom quickly, leaving the top raw or the underside scorched.
