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
- Egg yolks
- Egg proteins set and thicken the milk into a custard as they heat.
- Egg whites
- Whipped whites add structure and a lighter, airier texture to the custard.
- Milk
- Forms the liquid base that the eggs thicken into a smooth custard.
- Flour
- Starch helps stabilize the custard and keeps it from splitting or thinning.
- Brown sugar
- Caramelizing it creates the deep, toasty flavor and colour of the syrup.
The step that matters
Slowly stir the egg mixture into the hot milk until it thickens.. Adding hot milk to eggs gradually, while stirring, tempers them so the proteins thicken smoothly instead of scrambling or curdling. Heating too fast or too unevenly can make the custard grainy.
“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.
