Abbotsford farmer Bill Stewart has produced B.C.’s first Périgord truffle, a culinary delicacy that fetches up to $2,200 a kilo wholesale. The near-golf-ball sized fungus was unearthed by a truffle-sniffing dog in a seven-acre stand of specially inoculated hazelnut trees that Stewart planted nine years ago. Two more truffles have been unearthed since.
