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

What each ingredient does

Egg
Thickens the custard as it cooks and adds richness.
Cornstarch
Thickens the milk mixture into a smooth, sauce-like texture when heated.
Sweet milk
Forms the liquid base of the custard and gives it body.
Sugar
Sweetens the custard and balances its flavor.
Butter
Adds fat for a richer mouthfeel and smoother finish.

The step that matters

Cook the mixture until thick, stirring constantly. Cornstarch and egg thicken only when heated, and stirring keeps heat even so the starch swells smoothly without scorching or forming lumps. Stopping too early leaves the custard thin.
