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

What each ingredient does

Cornflour
Starch that swells in hot milk and thickens the mixture into a set, sliceable custard.
Milk
Liquid base that the starch thickens, giving the blancmange its creamy body.
Butter
Adds fat for richer flavour and a smoother, softer mouthfeel.

The step that matters

Boiling the thickened mixture. Cornflour starch only thickens fully once the mixture reaches a boil, and continuous stirring stops the starch clumping or scorching on the base of the pan.
