Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base that thickens into a creamy dressing.
- Corn starch
- Thickens the milk as it heats, giving the dressing body.
- Egg
- Adds richness and helps set the custard as it heats.
- Lemon juice
- Adds acidity that brightens the sweetness of the dressing.
- Sugar
- Sweetens the dressing and balances the lemon's acidity.
- Butter
- Adds fat for a smoother, richer mouthfeel.
The step that matters
Stir in the beaten egg while the mixture is boiling hot. Adding egg to very hot liquid can scramble it. Stirring constantly as the egg goes in lets it blend smoothly and cook into the thickened custard instead of forming lumps.
