Low-fat choc truffles

CALORIES: 53 EACH
MAKES: 24 truffles. PREP TIME: 30 minutes (plus 30 minutes chilling time). COOKING TIME: 5 minutes.
INGREDIENTS: 200g good-quality dark chocolate, six tablespoons strong, black coffee (such as espresso), two tablespoons clear honey, cocoa powder, to dust
METHOD: Melt chocolate gently in a large bowl over a pan of simmering water. Remove and set aside. It should look like a liquid pool of chocolate. Gently pour in coffee and stir until it thickens. The chocolate will start to “seize” and thicken almost instantly.
Add honey, a tablespoon at a time, slowly until you get a glossy mixture. Chill in fridge for 30 minutes or until the mixture has returned to a nearly solid form. Sieve three tablespoons cocoa onto a clean surface.
Scrape out a teaspoonful of the mixture into your hand and roll into a marble-sized ball (quickly so it doesn't melt in your hands!), then roll through the cocoa powder until fully coated and pop into a bowl or jar. Put the jar in the fridge, and you've got a indulgence that is not so naughty
