What each ingredient does

Gelatine
Sets the mixture into a firm, sliceable body as it cools.
Corn starch
Thickens the liquid when heated, giving the blancmange its smooth, creamy body.
Jam of your choice
Adds sweetness, fruit flavour and colour to the set mixture.

The step that matters

Cooking the corn starch fully. Corn starch only thickens properly once it is heated long enough to swell and gelatinize. If it is under-cooked, the mixture stays thin or chalky and can taste raw, and the final texture will be grainy rather than smooth.
