Chocolate Liqueur Truffles

Break chocolate up and place in a bowl with the brandy. Place bowl over a saucepan of simmering water. Stir gently to combine until the chocolate is smooth.

Stir in the butter and egg yolk until well combined (the heat from the chocolate will help melt the butter).

Refrigerate until firm enough to shape into balls - I made mine slightly larger than standard marbles, but it's up to you and your conscience! Roll each ball in the cocoa (or you could experiment with chocolate hail, crushed pistachio nuts, etc. I used drinking chocolate, as it's sweeter than plain cocoa).

Return to the fridge (or freeze, as desired). Serve chilled.
