Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Plain Omelet
Ingredients
Directions
Make the plain omelet
Take six eggs, leaving out the whites of two.
Beat them very lightly, and strain them through a sieve.
Add pepper and salt to taste.
Divide two ounces of fresh butter into little bits, and put it into the egg.
Have ready a quarter of a pound of butter in a frying-pan, or a flat stew-pan.
Place the pan on hot coals, and have the butter boiling when you put in the beaten egg.
Fry gently until a light brown on the underside. Do not turn it while cooking.
You may brown the top by holding a hot shovel over it.
When done, lay it in the dish, double it in half, and stick sprigs of curled parsley over it.
Vary the filling
Mix some parsley or sweet herbs minced fine, some chopped celery, or chopped onion with the beaten egg.
Alternatively, season with veal kidney or sweet-bread minced; with cold ham shredded finely; or with minced oysters (hard part omitted); or with tops of asparagus previously boiled, cut into small pieces.
Use a pan made specifically for omelets.
Make the soufflé omelet
Break eight eggs, separate whites from yolks, and strain them.
Put whites into one pan, yolks into another, and beat separately with rods until yolks are very thick and smooth, and whites a stiff froth.
Add gradually to the yolks three quarters of a pound of the finest powdered loaf-sugar, and orange-flower water or lemon-juice to taste.
Stir the whites lightly into the yolks.
Butter a deep pan or dish that has been previously heated, and pour the mixture rapidly into it.
Set it in a Dutch oven with coals under it, and on the top, and bake it five minutes.
If well made, turn the omelette soufflé out on a dish.
Serve
Do not begin to make an omelette soufflé until the company at table have commenced their dinner.
The whole must be accomplished as quickly as possible.
Serve immediately, or it will fall and flatten.
Send it round with a spoon.
If you live in a large town, hire a French cook to make and bake the omelette soufflé himself while the first part of the dinner progresses in the dining-room.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a structure when cooked, forming the body of the omelet and the soufflé's rise.
- Butter
- Fries the egg for browning and adds richness and a rich, buttery flavor.
- Powdered sugar
- Sweetens the soufflé mixture and helps stabilise the beaten yolks.
The step that matters
Stir the whites lightly into the yolks, then bake at once. Beaten whites hold air that makes the soufflé rise; overmixing knocks the air out, and a soufflé left to wait loses its height and falls as the trapped steam escapes.
Swap the onion
