Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the mixture and set into a firm, sliceable omelette as they cook.
- Bread crumbs
- Soak up the milk and add body, giving the omelette a softer, more tender texture.
- Milk
- Adds moisture and softness, so the omelette stays tender rather than dry.
- Flour
- Thickens the mixture slightly and helps it hold together when turned.
- Onion
- Adds savoury sweetness and aroma as it softens in the mixture.
The step that matters
Carefully turn the omelette over. The base must be set and browned enough to hold its shape. Turning too early can tear the omelette, because the uncooked egg and crumb mixture is still loose and fragile.
