Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Their proteins set when gently heated, thickening the custard into a rich, smooth base.
- Cream
- Supplies fat for a rich, smooth texture that stays creamy when frozen.
- Sugar
- Adds sweetness and keeps the frozen custard softer by limiting hard ice crystals.
- Caramel
- Adds deep caramel flavor and color to the custard.
- Vanilla
- Adds aroma that rounds out the dairy and caramel flavors.
The step that matters
Stir continually until thickened. Egg yolks scramble if they get too hot. Stirring over gentle heat keeps the heat even, so the proteins thicken the custard smoothly instead of curdling.
