About this recipe:I got the idea for this from The Garlic Farm where they've got a recipe for black garlic brownies and I thought if you could do it with dark chocolate brownies why not truffles too. Although if you don't like garlic (a lot) I wouldn't recommend this, I would say it was a bit like adding chilli to dark chocolate (a bit, not quite) oh and the only place I know of to get black garlic butter is the garlic farm web page.
Melt the garlic butter and chocolate together in a double boiler, or in a pan over barely simmering water, then put in the fridge to partially set until solid but still soft enough to poke a hole in easily.
Whisk the egg white and 20g of icing sugar together until you get soft peaks (not essential to get soft peaks but it helps with the texture). Mix the cocoa powder in to the egg mix. Add the soft chocolate and butter mix to the egg.
Form into balls then roll in the reserved icing sugar to finish. Place in the fridge to set fully until time of serving.
Always sieve your cocoa and icing sugar first to make things as easy as possible to mix in. You could also add some mint extract or put a hazelnut in the centre or you could crush some hazelnut or pistachios and add them to the mix or make a white chocolate truffle with added strawberry and use that in the middle or dust with cocoa instead of icing sugar or even do a milk chocolate with malt extract to. You could make a whole range of truffles with garlic if you wanted :-)
