Why it works: Butter and egg 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 ↓
Omelet, Plain
Ingredients
Directions
Prepare
Melt the butter in a frying pan.
Beat the eggs until frothy, then add salt and pepper.
Cook the omelet
Pour the eggs into the frying pan when the butter begins to frizzle.
Scrape the bottom of the pan with a tablespoon until the mixture is mostly lumpy and some liquid remains.
Lift the pan from the heat to reduce the temperature.
Push the omelet into a semicircle shape in the pan.
Hold the pan at an angle in front of the heat until the omelet is fully set.
Serve
Slide the omelet onto a hot dish using an egg slice and serve.

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
- Set into a tender structure as they cook, forming the body of the omelet.
- Butter
- Coats the pan and adds richness and flavor while keeping the eggs from sticking.
The step that matters
Lift the pan from the heat to reduce the temperature. Eggs proteins set quickly at high heat and turn tough or browned. Lifting the pan lowers the heat so the omelet cooks gently and stays tender.
