Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the custard, and beaten whites give the frosting an airy, light structure.
- Sugar
- Sweetens the custard and helps the yolks blend into a smooth base.
- Strong coffee
- Provides the coffee flavor and aroma that define the cake.
- Milk
- Supplies the liquid that, heated, thickens the custard along with the yolks.
The step that matters
Stirring in the boiling milk and coffee. Egg yolk proteins set as they heat. Stirring only until the mixture begins to thicken keeps it smooth; letting it boil can curdle or scramble the yolks, leaving a grainy texture.
