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 ↓
Chocolate Ice Cream
Ingredients
Directions
Prepare
Crush the junket tablet and dissolve it in 1 tablespoon of cold water.
Heat the milk, cream, and sugar to 98°F (37°C). Test the temperature by dropping a bit on the back of your wrist; it should feel neither warm nor cold.
Make the custard
Add the dissolved junket tablet and stir until thoroughly mixed.
Slowly add a little of the junket mixture to the melted chocolate, stirring constantly.
Combine everything, let it stand in a warm room until it jellies.
Finish
Cool and freeze.

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 sets into a soft, creamy body.
- Cream
- Adds fat for a richer, smoother texture.
- Junket tablet
- Its rennet enzyme curdles the milk so the mixture sets into a jelly-like custard.
- Sugar
- Adds sweetness and softens the frozen texture of the ice cream.
- Chocolate
- Supplies the chocolate flavor and some fat to the custard.
The step that matters
Heat to 98°F (37°C) before adding the junket. Rennet works best at body temperature. Adding it when the milk is too hot can destroy the enzyme, and if it is too cold the mixture will set slowly or not at all.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
