Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken and bind the mixture as their proteins set when heated.
- Cornstarch
- Thickens the mixture as it heats with the liquid, giving body without oil.
- Vinegar
- Adds acidity and sharp tang that balances the richness of the dish.
- Butter
- Adds fat for richness and a smoother, softer texture.
- Mustard
- Adds sharp flavour and helps stabilise the emulsified texture.
- Milk
- Adds moisture and a creamy body to the mixture.
The step that matters
Stir the egg mixture into the boiling vinegar. Egg yolk proteins set when heated and can curdle if the mixture overheats or is not stirred. Constant stirring keeps the mixture smooth while the cornstarch thickens it.
