A friend has recently decided to adopt a vegan diet. I was going over for dinner and at the last minute offered to make dessert - a vegan chocolate cake (simple, nothing weird about it - usually called "wacky cake" or some other such name) but didn't have anything in the house to top it with. Can't use whipped cream and didn't have any decent fruit. So I decided to make a chocolate ganache glaze using canned coconut milk instead of cream. Bingo. Works perfectly - no real coconut flavour to interfere with the chocolate and with a texture almost indistinguishable from a standard ganache. I haven't tried making truffles this way, but I'll bet it would be fine too. Excellent alternative for anyone who can't have or wishes to avoid dairy.
