Advent calendar chocolate truffles

Method

1. Put the chocolate, cocoa powder, vanilla and a pinch of salt in a large bowl. Pour the condensed milk into a heavy-based pan over a medium heat and cook, stirring regularly, until almost boiling. Once it’s very hot and steaming, pour it over the chocolate and stir until melted and combined. Set aside to cool at room temperature for 1-2 hours until thickened into a malleable, doughy consistency.
2. Meanwhile, prepare your coatings of choice by finely chopping or whizzing them in a food processor, then spread them out on separate plates.
3. Use your hands to roll the truffle mixture into balls about 2.5cm in size, then roll each truffle through one of the coatings until evenly covered. Set aside on a clean plate or board for 1 hour to set, then transfer to a box or wrap individually. Keep in an airtight container for up to 1 month.
