SKEWER a truffle and dip in melted chocolate. Top with a piece of hazelnut. Repeat with all truffles. Allow to set at room temperature then refrigerate until firm. Store in an airtight container, refrigerated, until required
Tips & Hints
If the chocolate becomes too thick for dipping, warm with a couple of short bursts of heat from a hair dryer, then stir very well. This mild heat helps to soften the chocolate without overheating and helps to maintain the temper of the chocolate and allow it to set at room temperature.
