Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg
Yolks thicken the custard, and the beaten white forms the light floating topping.
Milk
Forms the liquid base of the custard, which sets gently as it heats.
Sugar
Sweetens the custard and helps stabilise the beaten egg white.

The step that matters

Cooking the custard until it coats the spoon. Egg proteins thicken the custard as it heats, but if it overheats they scramble and it turns grainy. Stirring constantly and removing it from the heat at the right point keeps it smooth.

“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.
