Melt the chocolate and water together in 20 second blasts in the microwave, until thick and just melted (this is important!)

Add in the butter and stir until fully melted.

If you're adding alcohol or other flavourings add them in now, stirring until totally combined.

Pop into the fridge for at least 2 hours until set and firm.

Use a teaspoon to scoop out a small amount of mixture, roll into a ballwith your hands (messy!) and coat with icing sugar or cocoa powder.

Pop back into the fridge until fully set.
