Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base that the other ingredients thicken and flavor.
- Cornstarch
- Thickens the base as it heats, giving the ice cream body and a smoother texture.
- Egg
- Adds richness and helps bind the custard, adding body to the base.
- Cream
- Adds fat, which makes the frozen ice cream richer and softer on the tongue.
- Sugar
- Adds sweetness and lowers the freezing point, keeping the ice cream scoopable.
- Baker's chocolate
- Provides the chocolate flavor and color of the ice cream.
The step that matters
Combine the cornstarch mixture with the chocolate milk and stir well.. Cornstarch must be fully dispersed in cold liquid before heating, then stirred while the mixture heats, or it will form lumps instead of thickening the base evenly.
