AT A GLANCE
Serve biscuits such as shortbread to add texture to the silky jelly. Roasted hazelnuts or walnuts work well, too.
|01||For bitter chocolate jelly, stir sugar, coffee and 1 litre water in a large saucepan over medium-high heat until sugar dissolves, then bring to the boil. Remove from heat, add chocolate, stand for 5 minutes, then whisk until smooth. Squeeze excess water from gelatine, add to chocolate mixture, stir until combined, then set aside to cool slightly, whisking occasionally. Pour into a 2.25-litre fluted mould and refrigerate until set (4-5 hours).|
