Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

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.
- Potato flour or mashed potatoes
- Adds body and starch to the mixture, giving a softer, thicker texture.
- Lemon juice
- Adds a small amount of acidity that brightens the flavour of the eggs.
The step that matters
Cook the bottom until light brown, then flip. Egg proteins set from the bottom up, so flipping too early leaves the omelette runny and likely to tear, while cooking too long over medium heat can make it dry and rubbery.
Swap the potato
How well each one fits the dish's main ingredients (egg, pepper, nutmeg, lemon):
- Spinachfits better
- Capsicumfits better
- Shallotfits better
- Potatothe original
Fit is the average pairing score against egg, pepper, nutmeg, lemon. Candidates are from the same food group and used in at least 100 recipes.
