Why it works: Sugar and cream 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 ↓
Frozen Coffee Custard
Ingredients
Directions
Make the custard
Boil the coffee in the milk until it turns pale brown, then strain it back into the kettle.
Whisk together the eggs, cornstarch, and sugar, then add to the coffee mixture and cook until thickened.
Let the custard cool, then stir in the cream with dissolved sugar.
Freeze
Freeze the mixture in an ice cream maker according to the manufacturer's instructions.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks thicken the custard as they cook and add richness.
- Cornstarch
- Starch thickens the milk mixture so the custard becomes smooth and set.
- Cream
- Adds fat for a rich, smooth texture that softens the frozen result.
- Sugar
- Sweetens the custard and lowers its freezing point for a softer scoop.
- Coarse ground coffee
- Infuses the milk with coffee flavour and aroma.
The step that matters
Cook the custard until thickened. Egg and starch need enough heat to thicken the custard, but overheating can scramble the eggs. Cook gently and stir constantly to keep it smooth.
