Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Lemon Sauce
Ingredients
Directions
Make the sauce
In a bowl, beat together the butter, sugar, and egg yolks until well combined.
Add the grated rind and juice of the lemon, and mix well.
Slowly beat in the cream until fully incorporated.
Place the mixture in a basin over a pot of boiling water and stir until it thickens and becomes glossy.
Cool and serve
Remove from heat and set aside to cool on ice.
Serve cold with hot puddings or cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the sauce as they heat, giving it a smooth, glossy body.
- Butter
- Adds richness and a silky mouthfeel to the sauce.
- Sugar
- Sweetens the sauce and balances the sharpness of the lemon.
- Lemon
- Provides bright acidity and aroma from its rind and juice.
- Cream
- Adds moisture and richness, softening the sauce's texture.
The step that matters
Thickening over boiling water. Egg yolks thicken from gentle heat, around 70 to 80 degrees Celsius. If the water boils too hard or the sauce is overheated, the yolks can scramble and turn grainy. Stir steadily and watch for it to coat the spoon.
