Can a mustard be life-changing?

When Maille asked if I’d like to try their black truffle mustard, I scoffed at the price but, of course, said I’d be happy to give it a taste test.

Now, in our office, we’re already mad for Maille. The French condiment company is the king of Dijon as far as we’re concerned. So I was predisposed to like this mustard. But did I expect the flavor to be transformative? No. I was in no way prepared for the magic of Maille Chablis and Black Truffle Mustard.

What is Maille Black Truffle Mustard?

Presented in a sleek black stoneware jar, this mustard features a pungent, Chablis wine–infused Dijon base. That alone would be enough to make my taste buds dance. But Maille took it a step further, adding flecks of fresh black winter truffle for full-blown decadence.

My review of the most expensive mustard in the world

Intense is the best word for it. The flavor captures the best of Burgundy in a single, perfect bite. (And don’t forget, mustard has a long history as an aphrodisiac.)

You might think the tang of Dijon would overpower the black truffle, but no. From the moment you lift the cork stopper, the truffle aroma makes it clear, this is no ordinary mustard. It can turn a turkey or ham sandwich into something chic. Maille recommends adding it to mashed potatoes or risotto, but honestly, it’s just as good eaten straight from the spoon.

Why this black truffle mustard is worth the price

At around $43 per 4.4-ounce earthenware pot, it might be the most expensive condiment you’ll ever buy. I know it sounds crazy. But trust me when I tell you, the experience is worth every penny.

Maille’s Chablis and Black Truffle Mustard is made with care and craftsmanship, using premium ingredients and traditional methods. The result is a flavor that’s both bold and elegant, a mustard that demands attention.

A note on availability

Maille typically offers this mustard only during the autumn and early winter months to coincide with truffle season. However, according to Maille’s website, the black truffle mustard did not return this September. We’ll have to wait and see if it makes a comeback in the next truffle season.
