Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard as they set and add richness and a smooth texture.
- Milk
- Forms the liquid base of the custard and carries the chocolate flavor.
- Chocolate
- Provides the main chocolate flavor and color of the custard.
- Sugar
- Adds sweetness to balance the bitterness of the chocolate.
The step that matters
Adding the egg yolks. Egg yolks thicken by coagulating when heated, but if the custard gets too hot or is boiled after they are added, the proteins can curdle and turn grainy. Stir steadily and keep the heat moderate once the yolks go in.
