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 ↓

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 cook and give it a rich, set texture.
- Sugar
- Sweetens the custard and helps it turn light when beaten with the eggs.
- Cream
- Adds fat for a smooth, rich texture that softens the frozen result.
- Milk
- Forms the liquid base of the custard that the eggs set into.
- Strong coffee
- Provides the coffee flavour and aroma of the finished dessert.
The step that matters
Add the egg mixture to the hot milk and cook for a moment. Adding eggs to hot milk gently, while stirring, avoids scrambling. Cooking briefly thickens the custard so it sets smoothly rather than staying thin and grainy after freezing.
