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 set and enrich its texture, and the whites form the topping.
- Flour
- Thickens the milk and cream mixture so the custard holds its body.
- Cream
- Adds richness and fat, giving the custard a smooth, soft texture.
- Milk
- Forms the liquid base of the custard with the flour and sugar.
- Sugar
- Sweetens the custard and, whipped into the whites, helps the topping brown.
The step that matters
Beating in the eggs after removing from heat. Eggs added to a very hot mixture can scramble and turn grainy. Removing the pan from heat first lets the eggs blend in smoothly and thicken gently as the custard bakes.
