  4. Return to the saucepan, sweeten to taste, and boil gently for a few minutes.

Set and serve

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 blancmange as it cooks and cools.
Milk
Forms the liquid base that the arrowroot thickens into a creamy custard-like set.
Sugar
Adds sweetness to balance the mild flavor of the milk and arrowroot.

The step that matters

Mixing the arrowroot smoothly with cold milk. Arrowroot starch clumps if it meets hot liquid directly. Blending it with cold milk first lets the granules disperse evenly, so the thickened blancmange is smooth rather than lumpy.
