Squash blossom and Parmesan tacos

Chef Dustin Christofolo’s slow-food sensibilities make for a
memorable tasting-menu journey in South Phoenix.

Long ago when I showed up to work on a farm in Le Marche, Italy, the farmer said, after shaking my hand and meeting me, “I hope you like zucchini.” Good thing I did. For the next month, we ate zucchini at just about every meal: baked, stuffed, fried, twirled with pasta, tossed with salad and turned into soup. It was summer and zucchini was blooming.

On a recent summer night at Quiessence, there was zucchini in my pasta, soup and guinea hen. There were zucchini shavings garnishing pumpkin blossom, itself a close zucchini relative. There was even zucchini in my drink – dubbed a “ZucchiniTini.”

True farm-to-table cooking invites variety and, depending on the chef, creativity. When a kitchen is bound to what nature provides, food can get interesting.

Opened more than two decades ago, Quiessence, the fine-dining jewel of South Phoenix’s The Farm at South Mountain, has trended in a more creative direction over time. Served at big tables draped in white inside an early 20th-century house – or, weather permitting, set across a placid lawn outside – diners slow-play long meals channeling Arizona’s seasons. A few years back, chef-owner Dustin Christofolo renovated the kitchen, now a grand standalone space done in steel and mosaics where he offers an eight-course “chef’s table” tasting. Rank-and-file diners in the house are also bound to a tasting menu, with options of three to five courses.

What distinguishes Quiessence is its farm. The soil is its soul. Christofolo works with growers to select crops for the nearby “soil and seed garden,” which represents a small fraction of the farm’s 10-and-a-half growing acres. The farm, Christofolo says, is his “culinary director.”

And that’s how a long, heartfelt meal began with zucchini in my drink. The ZucchiniTini – essentially a gin martini spiked with zucchini water – adds a subtle, earthy twist to the classic. To go bolder, order the Drunken Peach, which is pretty much the gin-fueled cocktail version of biting into a ripe peach over the sink.

Drinks in hand, my wife and I listened to our waitress outline the menu’s pathways and detours, feeling welcome in the minimally adorned dining room. We opted for four-courses with a few add-ons. This middle option would take “two to two-and-a-half hours,” the server informed us.

The first course soon arrived: miso-zucchini soup. Slurps were delicate but rich, with miso just a whisper at the outer edge, almost like a touch of spice. Fried corn kept bites varied. It was a nice downtempo opener, a humble way to highlight summer produce.

Bowls cleared, an add-on arrived: a $14 oyster topped with mascarpone and caviar. It didn’t quite work, likely because the grilled oyster wasn’t cooked to the point that it turned rich and creamy, arriving rather just a bit warm. It was a blazing evening, and part of me wished the oyster had been icy and raw.

Even within the tasting menu model, Quiessence allows you to customize a bit. For the second course, I chose a beef tartare taco and my wife chose a pumpkin blossom. The latter arrived on a plate with dabs and swirls like a Jackson Pollock canvas, the fried blossom stuffed with a light egg filling. Basil aioli (dabs) and tomato coulis (spirals) lent flavor bursts and variety. The blossom was fresh and snappy. The tartare came as a “taco” in a crisp Parmesan shell. Its salty crunch had a nice hit of umami that paired well with the chilly beef. It was a refreshing few bites on a hot day.

After ordering a crisp white blend from Chateau Tumbleweed, one of several locals on the brief wine list, we were ready for pasta.

Christofolo takes pride in his pasta, which is derived from Hayden Flour Mills stone-milled grains and eggs sourced from his own chickens. For our meal, he plated half-moons filled with ricotta and duck confit under a flavorful wine reduction. The dough was rolled thick, making for a dense bite. It made for an enjoyable dish, if a bit complex for summer and pasta’s simple spirit, the warming sage and zucchini accents outgunned by the richness of the duck.

Next came the intermezzo: red pepper sorbet, a surprise highlight. What in the world is in this wild thing? was my first thought. The sorbet has all the intensity of red bell pepper, all those deep, round vegetal notes, only dialed up to unbelievable levels. It’s ice cold, a trace sweet. An incredible punch in the face of flavor.

At last, with the sun lowering over the house, entrées came. Striped bass was cooked perfectly, with crisp skin and tender meat. But even so, a Two Wash Ranch guinea hen leg stole the show. It had snappy skin and a soft, richly mineral interior. A vibrant plum gel and peach slice drew out its full minerality by contrast, anchoring the richness. Below the teetering leg hid pickled ramps, adding vibrant acidity and a mellow garlic kiss, all of it ringed by a simple zucchini puree. This was just outstanding.

By any measure, Quiessence is an important Phoenix restaurant. In a food scene that can feel clogged with out-of-state imports, Cisco and empty luxury dining, it’s nice to know that a homegrown standout is rocking with our soil and seasons. On my visit, summer darling zucchini starred. In the fall, Christofolo fills the table with charred eggplant, cranberry-pumpkin soup and Salt Spring Island mussels with lobster mushrooms, if past menus are any indication.

Sure, Quiessence isn’t flawless. In many ways, it’s like a peak-summer zucchini – grown bold and beautiful through the wind and elements, lying under the hard sun, a blemish here and a blotch there, not perfectly smooth, but glorious all the same.
