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 ↓
Omelette with Herbs
Ingredients
Directions
Prepare the omelette mixture
Boil semolina in milk until thick, then stir in a walnut-sized piece of butter and let cool.
Once cool, stir in beaten eggs (yolks and whites separately).
Add chopped onion and parsley to the egg mixture.
Fry the mixture as you would for a regular omelette.
Bake the eggs and tomatoes
Butter the molds and break an egg into each.
Add a dusting of pepper and salt, and a small dab of butter on top.
Bake in the oven until set.
Grease a baking tin and place red tomatoes inside.
Add a dab of butter on each tomato, dust with pepper and salt, and bake until soft.
Serve
Serve the eggs and tomatoes alternately on a plate, sprinkled with chopped parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set to bind the omelette and give it a firm, tender structure when cooked.
- Semolina
- Thickens the milk into a body that gives the omelette more substance and a softer texture.
- Milk
- Cooked with semolina to form a thick base that adds moisture to the mixture.
- Butter
- Adds richness and fat, contributing flavour and a tender texture to the eggs.
- Red tomatoes
- Soften when baked, adding moisture, acidity and sweetness alongside the eggs.
The step that matters
Bake until set. Eggs turn from liquid to solid as proteins coagulate with heat. Overbaking makes them rubbery and dry, while underbaking leaves them runny in the centre.
Swap the onion
How well each one fits the dish's main ingredients (parsley, egg, pepper, butter, tomato, semolina, milk):
- Capsicumfits better
- Potatofits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against parsley, egg, pepper, butter, tomato, semolina, milk. Candidates are from the same food group and used in at least 100 recipes.
