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
Soak gelatin in ½ cup cold milk for 5 minutes.
In a farina kettle, bring the remaining milk to a boil.
Grate chocolate into a bowl.
Add eggs and sugar to the chocolate; beat until well mixed.
Dissolve gelatin in hot milk.
Stir the dissolved gelatin gently into the egg mixture.
Make the custard
When chocolate is melted, combine it with the milk mixture in the farina kettle.
Place the kettle over hot water.
Stir until the custard thickens slightly, but do not boil.
Strain the custard and let it cool.
Freeze and churn
Once cool, freeze the mixture until quite stiff.
Carefully open the freezer and fold in the whipped cream.
Churn until very stiff.
Pack the ice cream as you would plain ice cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the custard as they set with gentle heat, giving richness and body.
- Gelatine
- Adds firmness to the frozen custard so it holds its shape and resists iciness.
- Sweetened chocolate
- Provides the main flavor and, with the milk, forms the base of the custard.
- Cream
- Folded in before churning to add fat, smoothness and a lighter, creamier texture.
- Sugar
- Sweetens the custard and lowers its freezing point, keeping it softer when frozen.
The step that matters
Stir the custard over hot water without boiling. Egg proteins thicken the custard gently; if it boils, the eggs can curdle or scramble, leaving a grainy texture.
