What can you do with a bowful of ganache, intended for truffles, which is rock hard at room temperature, crumbly, and showing signs of seizing? Some might throw it into the bin, but I'm a thrifty, frugal cook, and it goes against my nature to throw away 350g of chocolate and double cream (even if FB paid for it, and it was her attempt at truffles which went wrong!)
It seemed a shame to dilute it further to make a sauce, but I wasn't sure it would ever set hard enough for trufles after so much milk had been added, so instead I quickly beat in two egg yolks, and then folded in the stiffly beaten egg whites, to make a mousse. It was still a bit of a gamble as to how well it would set, but I'm pleased to say it made a very light, soft mousse. Because the original chocolate was 85% cocoa solids, and the only added sugar was in the white chocolate and amaretto, it still tasted rich and delicious, although not as deeply chocolatey as a traditional mousse using just eggs and chocolate.
