There are some meals that are unforgettable.

And then there’s the winter truffle menu at Chef Mavro in McCully.

It’s not a meal you’d easily forget — but it’s one you wouldn’t want to.

It all started with this menu:

I browsed the lineup: steamed day-boat onaga (long-tail red snapper) done Chinese style, a decadent wagyu pavé with a pomegranate-teriyaki glaze, a Waialua chocolate crispy rice bar.

And wine, too?

I felt like Christmas came early!

My husband and I were invited by chef/owner George Mavrothalassitis and his lovely wife, Donna Jung, to sample the winter truffle dinner menu, which is available now through the holidays. (Incidentally, today is the 16th anniversary of Mavro’s restaurant!)

The menu features the exquisite Périgord truffles (above), often referred to as the “Diamonds of Périgord.” These truffles are characterized by a subtle aroma and an earthly flavor somewhat reminiscent of a rich, dark chocolate. Like other varieties of truffles, these grow underground and are hunted by dogs (used to be pigs). They’re rare, too, scarcer and more desirable than others, making this menu at Chef Mavro that much more spectacular.

And if anyone knows how to use Périgord black truffles, it’s Mavro.

Here’s what we ate — and yes, you can eat this, too:

I love a good amuse bouche. Chill some carrot soup, add some coconut foam and top with cocoa nibs, and I’m sold.

This is the vegetable course, a méli-mélo (collection) of root vegetables accented with black truffle shavings, some baked, others braised, and a few raw. As Mavro says, if it’s better not to cook them, they don’t.

One of the best dishes I have all year is this: the restaurant’s classic Peterson Upland Farm egg and truffle “osmose,” whereby the eggs are stored with the black truffles upon arrival in a hermitically sealed box. Yes, they are sealed together. That way, the eggs are naturally infused with the truffle aroma. (Hence, the “osmose” in the name.) The egg is then poached to preserve the truffle flavor and served in a truffle potato mousseline, topped with pickled shallots, prosciutto ribbons, chervil leaves and even more truffles on top. It is ridiculously, almost criminally good.

Next, this is the steamed day-boat onaga, done Chinatown style, with ginger shiitake mushrooms, sizzled with grape seed and sesame oils, and topped with crispy fried cilantro and green onions that gave the dish a little something extra. Mavro really knows how to cook fish, can I just say.

Here’s the lamb loin with a deconstructed basil-infused ratatouille and Provencal socca (chickpea flour crepes), inspired from the French Riviera, Côte d’Azur. It was finished with a nice sweet-spiced lamb jus and topped with some black truffle shavings.

This it the 100 percent wagyu pavé topped with a well-balanced pomegranate-teriyaki glaze. In one corner is sautéed kabocha (pumpkin) topped with a bouquet of watercress from Sumida Farms. And in another corner are potato mochi cakes with a yuzu-kosho accent in the middle. The best bite had all of the components, trust me.

Next up: the pre-dessert. (Don’t you love pre-desserts?) This is a champagne gelée with honeydew melon. The perfect palette cleanser.

We were treated to two desserts last night. This was mine — Mavro knows me! — a Waialua chocolate crispy rice bar with cranberry white chocolate namesake, gingerbread cake with a tangy cranberry sauce, topped with candied almonds. Divine!

My husband had the rosemary roasted pineapple with semifreddo, a guava gelée, coconut (haupia, more like) sorbet, and sansho crumble. Such a delightfully refreshing dish.

We even got to sample the popular white chocolate and green tea marquise. Such a lovely dessert.

And if that weren’t enough, we were gifted with rich dark chocolate and lavender pavé (truffle) that melted in our mouths. The perfect ending.
