Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Eggs, Frothed
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the omelet
Mix the lemon juice with water and beat in the egg yolks and 4 egg whites.
Sweeten to taste and add a pinch of salt.
Pour the mixture into an omelet pan and fry carefully for about 5 minutes.
Top and brown
Whip the remaining 4 egg whites with 1 pound of fine sugar until frothy, adding vanilla or lemon extract if desired.
Place the omelet on a dish and heap the frothy eggs over it.
Brown lightly in the oven at 350°F (175°C) or before the fire.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Enrich the omelet, adding richness and a tender, custard-like texture when cooked.
- Egg whites
- Whipped with sugar, they form a light foam that gives the frothy topping its airy structure.
- Fine sugar
- Stabilizes the whipped egg whites and adds sweetness to the frothy topping.
- Lemon juice
- Adds acidity that brightens the flavor and helps stabilize the eggs.
The step that matters
Whip the remaining egg whites with sugar until frothy. Egg whites trap air when beaten, forming a foam that sets with heat. Underwhipped whites stay runny and deflate, while overwhipped whites turn dry and grainy. Adding sugar gradually helps keep the foam stable.
Swap the lemon
The recipe marks lemon as optional. How well each one fits the dish's main ingredients (egg, sugar, vanilla):
- Figfits better
- Blueberryfits better
- Peachfits better
- Lemonthe original
Fit is the average pairing score against egg, sugar, vanilla. Candidates are from the same food group and used in at least 100 recipes.
