Ingredients
Directions
In a saucepan, stir together the sugar and egg yolks until well combined.
Add the lemon juice and cook slowly over low heat, stirring constantly.
Once the mixture thickens, add the walnut-sized piece of butter and stir until melted.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the dressing as they cook and set, giving it a creamy body.
- Sugar
- Sweetens the dressing and balances the sharpness of the lemon juice.
- Lemon juice
- Adds acidity and bright flavor that cuts through the richness of the yolks.
- Butter
- Adds richness and a smooth, glossy finish to the dressing.
The step that matters
Cook slowly over low heat while stirring constantly. Egg yolks thicken through gentle heat, but if they get too hot they scramble into lumps. Constant stirring spreads the heat evenly so the dressing thickens smoothly.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, egg, lemon, butter):
- Almondfits better
- Pistachiofits about as well
- Walnutthe original
- Milletfits about as well
Fit is the average pairing score against sugar, egg, lemon, butter. Candidates are from the same food group and used in at least 100 recipes.
