Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Corn starch
- Thickens the milk mixture into a smooth sauce as it heats.
- Egg yolks
- Enrich the sauce and add body and richness when cooked.
- Egg whites
- Beaten to stiff peaks, they add lightness to the finished sauce.
- Chocolate
- Provides the chocolate flavor and deep color of the sauce.
- Milk
- Forms the liquid base that the sauce thickens in.
The step that matters
Stirring the egg mixture into the boiling chocolate sauce. Egg yolks can scramble if added to very hot liquid too quickly. Stirring constantly while adding the egg mixture and cooking briefly helps it blend smoothly and thicken evenly.
