Why it works: Egg and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 106,462 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Omelet
Ingredients
Directions
Prepare the eggs
Beat the egg whites and yolks separately.
To the yolks, add salt and cream mixed with flour until smooth.
Gently fold in the beaten egg whites.
Cook
Heat lard in a skillet until very hot but not smoking.
Pour the egg mixture into the skillet and cook until the bottom is a rich brown.

Egg and flour barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trapped by beating and folded in give the omelet its light, airy structure.
- Flour
- Adds a little body to the yolk mixture, helping it stay smooth and hold together.
- Rich cream
- Adds moisture and richness, keeping the omelet tender rather than dry.
- Lard
- Fat in the skillet that conducts heat and helps the bottom brown.
The step that matters
Heating the lard until very hot but not smoking. If the fat is too cool, the omelet absorbs it and turns greasy and pale; if it smokes, the fat burns and gives a bitter taste and scorched bottom. The right heat sets the base quickly and browns it evenly.
