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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set with heat to form the body of the omelette and hold the roll together.
- Potatoes
- Form the filling, adding bulk and a soft, tender texture inside the roll.
- Flour
- Thickens the egg mixture and gives the omelette more body.
- Milk
- Loosens the egg mixture so the omelette stays tender rather than tough.
- Butter
- Adds richness and helps the omelette brown in the skillet.
- Grated cheese
- Melts and browns on the surface, adding savoury flavour.
The step that matters
Shape the omelette into a roll. Shape the omelette while it is still warm and pliable. As egg proteins cool they firm up and lose flexibility, so a cold omelette is more likely to crack when rolled.
Swap the potato
How well each one fits the dish's main ingredients (egg, milk, butter, flour, cheese):
- Potatothe original
- Asparagusfits about as well
- Chivefits about as well
- Sweet potatofits less well
Fit is the average pairing score against egg, milk, butter, flour, cheese. Candidates are from the same food group and used in at least 100 recipes.
