Why it works: Egg and lemon are a kitchen classic. They rank in the top 19% of all ingredient pairs, and cooks put them together in 44,316 recipes. Both carry (e,e)-2,4-decadienal, which smells fatty, deep fried. The science ↓
Asparagus with Hollandaise Sauce I
Ingredients
Directions
Prepare the asparagus
Wash fresh asparagus, cut off tough ends, and tie in bunches so they stand erect in boiling water.
Keep the tips out of the water while it boils, as they cook more quickly and become too soft.
When tender, remove from water, drain, and keep hot until served.
If using canned asparagus, drain it, cover with boiling water, then while hot serve with the sauce.
Make the Hollandaise sauce
To make Hollandaise sauce, whisk ½ cup soft butter, 2 egg yolks, 1 tablespoon vinegar or 1 tablespoon lemon juice, 1 teaspoon salt, and cayenne to taste.
Place about half the butter, the lemon juice, and the eggs in a saucepan that is in a larger pan containing hot water.
Stir constantly; as it thickens, gradually add the rest of the butter.
If the sauce gets too hot and separates, keep the water in the lower pan hot but below boiling.
When thickened, remove from heat, add salt and cayenne, and serve immediately.

Egg and lemon barely smell alike, yet cooks put them together in 44,316 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
- Egg yolks thicken the butter into a stable, emulsified sauce when gently heated.
- Butter (in the method)
- Provides fat and richness, forming the body of the emulsified sauce.
- Lemon juice
- Adds acidity that brightens the rich butter and egg flavour.
- Vinegar
- Adds acidity that brightens the sauce and helps stabilise the emulsion.
The step that matters
Keep the sauce gently heated and stir constantly. Egg proteins thicken the sauce when warmed gently, but too much heat scrambles them and the butter separates out. Keeping the outer water below boiling and stirring constantly prevents this.
Swap the lemon
