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

What each ingredient does

Eggs
Set when heated, thickening the custard and giving it body.
Flour
Its starch thickens the milk mixture as it cooks.
Milk
Forms the liquid base that thickens into the custard.
Sugar
Sweetens the custard and helps keep it smooth.

The step that matters

Cooking the custard thoroughly. Flour starch only thickens fully once the mixture is hot enough, so the custard must be stirred until it cooks through. Stopping early leaves it thin and floury, while stirring too little lets it scorch or lump on the bottom of the pot.
