Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Proteins set as they warm, thickening the milk into a custard.
- Milk
- Forms the liquid base, giving the sauce its body and creaminess.
- Saccharin
- Provides the sweetness.
- Vanilla
- Adds aroma and its characteristic flavor.
The step that matters
Cook over gently boiling water, stirring constantly until thick.. Egg proteins thicken the custard as they warm, but if they overheat they scramble and curdle. Gentle heat and constant stirring keep the sauce smooth and evenly thickened.
“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.
