HOW MUCH would you pay for a tub of mustard? Five dollars? Fifteen dollars, if it was from the food hall at David Jones?

How about $100 per 100 millilitres? That's how much the world's most exclusive mustard will set you back.

The Maille Chablis white wine and black truffles mustard , as it's known, is produced over a five month period each year in France. With ingredients such as wine sourced from Chablis, the renowned Burgundy wine region, and black truffles sourced from the Drome region, the mustard is said to have"woody, intense and rich" notes.

Flown directly from the pump in Paris La Madelaine to the new La Maison Maille Shop in Victoria's Mornington Peninsula, the mustard is a recommended condiment for everything from scrambled eggs, lamb and capon to scallops, red meats and white meats.

"You wouldn't cook a premium cut of beef and scrimp on the condiments," Good Chef, Bad Chef and Maille Ambassador Adrian Richardson said.

"Quite often, it's actually the condiments that become the hero of the meal as they enhance and highlight each and every dish. No matter the meal, from your first bite to your last, the mix of flavours combined with premium ingredients is the recipe for the perfect dining experience," he said.

This fancy spread is right up there with the world's most expensive cupcake, the Golden Phoenix, or the diamond-laced cocktail the Ritz-Carlton in Tokyo serves up. Thankfully, the white wine and black truffles mustard is much more accessible - you only need travel as far as the new La Maison Maille store in Mount Eliza to try it, and many more mustardy delights.
