Why it works: Cream and sugar are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Boiled Ice Cream
Ingredients
Directions
Make the custard
In a large pot, bring the sweet milk and sweet cream to a boil.
Dissolve the corn starch in a little milk.
In a bowl, beat the eggs and mix in the sugar until well combined.
Pour the corn starch mixture into the boiling milk and cream, stirring well.
Add the egg and sugar mixture, stirring continuously until it comes to a boil again.
Cool and freeze
Remove from heat and let cool completely.
Once cooled, freeze the mixture.
Add flavoring to taste before freezing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Corn starch
- Thickens the milk and cream into a smooth, creamy base as it heats.
- Eggs
- Add richness and help set the custard as it is brought to a boil.
- Sugar
- Sweetens the base and softens the texture of the frozen cream.
- Sweet cream
- Adds fat for a rich, smooth texture.
The step that matters
Stirring the egg and sugar mixture while it comes to a boil. Eggs can scramble or curdle if they overheat in one spot. Constant stirring keeps the heat even so the custard thickens smoothly.
