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

What each ingredient does

Arrowroot
Thickens the milk into a smooth, set jelly as it cooks and cools.
Milk
Forms the liquid base that the arrowroot thickens into a creamy jelly.
Sugar
Sweetens the jelly to taste.

The step that matters

Stirring the arrowroot into boiling milk. Arrowroot must be stirred in smoothly so it disperses before thickening; adding it to milk that is not boiling, or letting it sit, can leave lumps and a weaker set.
