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

What each ingredient does

Egg whites
Beaten into a stiff foam that sets with gentle heat to form the floating islands.
Sweet milk
Serves as the hot liquid base that cooks the yolk mixture into a custard.
Sugar
Adds sweetness and helps stabilise the beaten whites.

The step that matters

Pouring the hot milk over the yolk mixture. If hot milk hits the yolks too quickly or is not stirred constantly, the yolks can scramble into lumps. Adding the hot liquid gradually while stirring warms the yolks evenly so the custard thickens smoothly.
