  4. Melt the remaining half of the gelatin in a little milk and stir it into the chocolate mixture.

  5. Let both mixtures cool.

Layer and set

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

What each ingredient does

Gelatine
Sets the milk and coffee mixtures into a firm, sliceable dessert.
Milk
Provides the creamy body and smooth texture of the blancmange.
Coffee
Gives the dessert its coffee flavour and a slightly bitter note.
Chocolate
Adds chocolate flavour and a deeper colour to the chocolate layer.

The step that matters

Melting the gelatine fully before stirring it in. Gelatine only sets properly when fully dissolved; undissolved granules leave gritty specks and weak spots. Stirring the dissolved gelatine evenly into each warm mixture prevents clumps and uneven setting.
