Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Potato Omelette
Ingredients
Directions
Prepare
Beat the yolks and whites of the eggs together.
Thin the mashed potato with the milk and strain through a colander.
Stir the potato mixture into the eggs.
Cook and serve
Heat butter in a pan until warm, then pour in the mixture.
Shake the pan and loosen the omelette with a spatula.
When nearly done, hold the pan under a broiler to brown the top.
Invert the pan over a very hot dish and turn out the omelette without folding.
Serve immediately, as it will fall quickly.

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, giving it body.
- Mashed potato
- Adds body and moisture, giving the omelette a tender, soft texture.
- Milk
- Thins the potato so it blends smoothly and keeps the omelette moist.
- Butter
- Fat for frying that prevents sticking and adds richness and browning.
The step that matters
Hold the pan under the broiler only when nearly done. Egg proteins set quickly under high heat, so the top can brown and over-firm while the centre is still runny. Watching closely keeps the omelette tender and evenly cooked.
Swap the potato
How well each one fits the dish's main ingredients (egg, milk, pepper, butter):
- Capsicumfits about as well
- Potatothe original
- Asparagusfits about as well
- Chivefits less well
Fit is the average pairing score against egg, milk, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
