Ingredients
Directions
Make the base
In a double boiler, heat the cream over simmering water, stirring often.
Remove from heat when the water boils, then add sugar and flavoring, stirring until the sugar dissolves.
Let the mixture stand for a few minutes, then strain it into a freezing can.
Freeze
Freeze the mixture until it reaches a creamy consistency.

What each ingredient does
- Rich cream
- Provides fat that makes the ice cream rich and smooth-textured.
- Sugar
- Adds sweetness and keeps the frozen mixture softer and easier to scoop.
The step that matters
Heating the cream in a double boiler. Gentle, indirect heat from simmering water warms the cream without scorching it, since dairy can burn or stick on direct heat. Stirring often spreads the heat evenly.
