The Guinness Book of World Records for the most expensive cheesecake was awarded to New York’s Raffaele Ronca's $5,000 (EUR 4,200) pie on Wednesday. The cheesecake includes eye-watering expensive ingredients such as water buffalo, 200-year-old cognac and white truffles from Alba and 24 carat gold. The crust is made from biscotti and the chef's own chocolate and hazelnut spread. Alba truffles... Еще, sniffed out of the Italian countryside by specially trained dogs, are the diamonds of the truffle world. They typically sell for more than $4,000 a pound.
