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

What each ingredient does

Sea moss
Its natural gelling compounds thicken the milk as it cooks, giving the blancmange its set.
Milk
Forms the liquid base that thickens and gives the dessert its creamy body.
Sugar
Adds sweetness to the finished blancmange.
Cinnamon
Infuses the milk with warm aroma when boiled in it before straining.

The step that matters

Cooking the sea moss in the milk until it thickens. Sea moss only gels once the milk is heated enough to draw out its thickening compounds. If the milk is not cooked long enough, the blancmange will stay thin and fail to set when cooled.
