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 ↓

Ingredients
Directions
Make the mixture

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potato flour or mashed potatoes
- Provides starch that thickens the egg mixture and gives the omelette a soft, body-filled texture.
- Eggs
- Set when heated to bind the mixture into a cohesive omelette with structure.
The step that matters
Cooking until thick before frying. Eggs set as their proteins coagulate with heat. If the mixture is not cooked until thick, it may break or stay runny, so it holds together when turned or served.
Swap the lemon
The recipe marks lemon as optional. How well each one fits the dish's main ingredients (potato, egg, pepper, nutmeg):
- Lemonthe original
- Limefits about as well
- Cherryfits less well
- Figfits less well
Fit is the average pairing score against potato, egg, pepper, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
