This picture arrived recently from Australia: I am both jealous and salivating...
Nick Malajczuk looks (unsurprisingly) rather pleased with his 1kg+ monster truffle.
I've been doing some checking up on NZ's largest truffle. Alan Hall believes the biggest he has ever found was about 760g (and there's a picture of what might be it on his web site), but his brother Ian believes that a bigger one turned up at about the same time ('97 or '98). Still, it looks as though Nick's claim to the largest black truffle found outside Europe is justified. Congratulations! Thanks for the picture Nick, it's going in the book...
