Preparation time: 30 minutes
Chilling time: minimum 3 hours or overnight
275g organic dark chocolate (minimum 60% cocoa solids, broken into pieces)
250ml organic double cream
50g unsalted organic butter, at room temperature
50g cocoa powder
1. Place the chocolate in a large bowl. Bring the cream to the boil and pour it over the chocolate. Stir gently until the chocolate has melted, trying not to create bubbles. Leave to cool for 2 minutes, then add the butter in two stages and stir in gently. Once the butter is incorporated, the ganache should be smooth and glossy with no oil slick on the surface. Set the truffle mixture in the fridge for a minimum of 3 hours or overnight.
2. Remove the ganache from the fridge about 15 minutes before you want to make the truffles, depending on room temperature.
3. Put the cocoa into a bowl. Ensure your hands are cold and dry, then dust them with cocoa. Take spoonfuls of the ganache mixture (use a teaspoon or a tablespoon, depending on how large you like your truffles) and roll the mixture into a ball in your cocoa-dusted hands.
4. Drop each shaped truffle into the bowl of cocoa, turn it around and then toss it between your palms to remove any excess powder. The truffles can then be returned to the fridge and kept for up to 2 days as long as they are stored in an airtight container.
HINT: These truffles can be eaten directly from the fridge or allowed to come to room temperature. The colder the truffle, the less dry and dusty the cocoa will seem when eating it.
