Sabatino Truffles, one of the largest truffle suppliers in the world, unearthed the largest white truffle on record in central Italy this week.

Weighing in at a massive 1.89kg (4.16 pounds), the truffle is almost twice the size of the existing Guinness record holder and dwarfs oranges.

Offers have already come in from Macau, China and Dubai to buy the largest truffle in the world for $1 million.

Edible truffles are held in high esteem in French, Georgian, Greek, Italian, Middle Eastern and Spanish cooking, as well as in international haute cuisine. Truffles are a type of ectomycorrhizal fungi and are usually found around the roots of trees. Truffles are usually round, warty, and irregular in shape and vary from the size of a walnut to that of a man’s fist.

White Truffles are found only by using specially trained dogs in northern and central Italy during the months of October, November and December. The Italian white truffle is considered to be superior in smell and taste to the French black truffle. Known for it’s pungent aroma, White truffles are the rarest and most coveted food ingredients in the world.

The Balestra family of Sabatino Truffles will auction the giant truffle off in New York City next week at Sotheby’s and donate the proceeds to a charity of their choice.
