Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Thickens the sauce as it gently sets when warmed, and adds richness.
- Cornflour
- Thickens the liquid into a smooth sauce as its starch swells when heated.
- Butter
- Adds fat for a rich, smooth mouthfeel and flavour.
- Lemon juice
- Provides acidity for a sharp, bright flavour that balances the richness.
The step that matters
Stirring in the egg mixture. Egg proteins set at higher temperatures, so adding the egg to a hot sauce can scramble it. Removing the sauce from the heat first and stirring gradually keeps the mixture smooth and prevents curdling.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
