While the truffiere's first truffle was harvested in the cold soil of Tasmania's Huon Valley in 1999, the Robertson trufferie was established only seven years later by then owner Ted Smith. It shot to truffle stardom when the farm yielded Australia's largest truffle, a French black perigord weighing 1.11kg, worth roughly $2000. That record still stands today, and as I wander into the truffiere – as a truffle orchard is known – it's easy to spy the crazed earth where little truffles are starting to erupt from their cold beds.
Tanya kneels beside a patch of broken soil reverently. "Oh look, this one's crowning!" she says excitedly. And there, peering out from the ground, is the unmistakable shape of a black truffle. Tanya coos to the precious fungus as she sweeps the dirt from around it and oh, so gently levers it from the earth.
The truth is undeniable – truffles are no supermodels. Lumpy, misshapen and dark brown, they are rough to the hands as hundreds of tiny sharp pyramids make up their skin, and when sliced open, a cross-section of the coffee-coloured fungus is a web of black veins.

The truffiere comprises perfectly straight rows of around 300 English oaks, cloaked in their autumn colours, and the smaller, evergreen holly oak.
"The first week of June is the official beginning of the truffle season, although it will probably start earlier, from what we see happening in the truffiere," says Tanya.
Singles, groups, hen's parties and millennial foodies are all drawn to Robertson Truffle's weekend truffle hunts. "We've even got a wedding proposal happening soon – he wants to plant a ring in a truffle for his girlfriend to discover!" says Tanya.
While we've had no trouble unearthing several truffles, the harvest is traditionally aided by truffle pigs. "But can you imagine holding a huge pig back from eating the truffles?" asks Tanya.
This year, the farm expects to produce its biggest haul of truffles.
As on cue, we hear a loud baying and Seal and Archie bound out of their car – the truffle dogs have arrived! The two glossy American Labradors catch scent of the fungi and it's noses to the ground and tails in the air.
"Show me!" command their handlers, Marilyn and Lee-Ann, and the dogs point their noses toward the truffles.
This year, the farm expects to produce its biggest haul of truffles, including their first ever summer truffles, which are smaller and less pungent than their black cousins, and also easier on the wallet.
Which brings us to price. At $3 a gram, or $300 a kilogram, truffles demand some cosseting.
After we lift a handful of little fungi from the ground, Patrick brushes the truffles then gently washes them clean in preparation for lunch, which is served on long benches by the farm's fire pit. I smother thick wedges of sourdough in truffle-flecked butter and Tanya serves a cheesy quiche over which she grates a truly generous amount of truffle.

"I also make shortbread truffle cookies, and the smell when they're cooking fills the whole house," she says. The scent – a renowned aphrodisiac – is musky and earthy, pungent and intoxicating.
"Sometimes, we just put fresh eggs in a jar with a truffle, and it infuses its fragrance into the eggs for truffled scrambled eggs, without having to even cut the truffle," adds Patrick, as we move to the warmth of the sunny farmhouse kitchen, where their giant Irish wolfhound, Aisling, lazes in the afternoon sun.
