If you were a single Slavic pagan in ancient times, the path to finding true love was fairly straightforward and considerably more exciting than going on a blind date. All you had to do was weave a garland of wildflowers, grab your intended by the hand, hurl yourselves over the roaring flames of a bonfire, and plunge nude into the nearest body of water.

In other words, ancient midsummer festivals of romance were fairly high stakes.

While you likely won’t find anyone risking third-degree burns or stripping nude in Boulder this weekend, chef Bo Porytko is reviving similar energy for a sprawling 10-course fine-dining experience where feast-goers can party like it’s 900 A.D.

The Midsummer Farm Dinner takes place on Sunday at Esoterra Culinary Garden, 8985 Valmont Road, Boulder. The event will bring together a collective of 10 chefs from some of Denver’s buzziest restaurants  — including Molotov, Somebody People, Hearth, Odell’s Bagel, Petit Chelou, Margot, Bear Leek, La Diabla and Rougarou — for a collaborative, long-table meal built around Esoterra’s summer produce. The outdoor feast will begin with arrivals at 5 p.m., followed by dinner at 6 p.m. Tickets start at $260.

Porytko, the chef behind Denver’s Molotov restaurant, said the dinner series was inspired by his heritage.

“In Ukrainian culture, we have something called Ivana Kupala, which dates back to ancient times,” Porytko said. “Basically, it’s their midsummer festivities that also act as a mating holiday.”

Don’t worry, coupling up is not required for this event.

“Midsummer is just kind of a fun time,” Porytko said. “It was a good way to harness these weird, culty vibes that kind of suit the farm setting.”

The ancient East Slavic festival of Kupala was celebrated on the evening of June 23-24.

For guests wondering how that ancient atmosphere translates to a modern dinner on a 100-acre Boulder property, the evening starts on a hospitable note. Guests arrive for James Beard-recognized cocktails mixed by the team from Denver’s Yacht Club. From there, diners have time to explore the farm.

“The way the actual event begins is people come to the farm and get about an hour with welcome cocktails,” Porytko said. “Then you’re supposed to wander, check out the space, take in the farm, and there’s a little bit of education too.”

Attendees are asked to arrive dressed entirely in white. An LED flower wreath will be placed at each setting around a massive table built for 100 people. A maypole will be erected nearby, and a live DJ will guide the evening’s soundtrack. The music will begin to vibe with standard dinner fare before veering into unexpected territory.

“The DJ will play normal music, but then take, for example, a Kelly Clarkson song and turn down the beats per minute so she sounds like she’s speaking in Viking tones,” Porytko said, adding that the DJ will also mix in random Gregorian chants to fit the scene.

As the wine flows, the initial formality of the long table quickly disappears. Porytko said guests naturally start getting up, making friends and moving around the property after a few courses.

“After 10 courses and eight glasses of wine, people just kind of take it in whatever direction they want,” Porytko said.

To translate those festive vibes into an actual 10-course meal, the participating chefs rely on a highly democratic planning process. Justin Freeman, the executive chef of Somebody People in Denver, will help coordinate the logistics, beginning with a digital inventory of whatever Esoterra is currently pulling from the soil.

“There’s a Google Doc that we all use,” Freeman said. “We just ask the owner of Esoterra — Mark DeRespinis — what he’s growing, and then everyone signs up for what ingredients they want to cook with. We really just try to showcase what Mark has.”

Chefs look over the active list, claim the specific vegetables they want to work with and design a dish around them. Freeman then steps in to help arrange the final layout of the courses. He said the event has become an ongoing annual collaboration to give a little praise to the people who are doing all the hard work — the farmers.

The resulting menu leans heavily into hyper-seasonal creativity, starting with Porytko’s own intricate contribution.

“The idea is to highlight items from the farm,” Porytko said. “For me, I’m highlighting their beets, their Badger Flame beets.”

Porytko is preparing a guinea hen roulade cured in the juice of the Badger Flame beets and stuffed with a chocolate mint mousseline. The dish will be served with a beet mole, a gummied Badger Flame beet and traditional roasted beets.

The rest of the collective will showcase the farm’s harvest through a variety of distinct culinary styles. Freeman is serving grilled fennel with a creamy pistachio sauce, pickled celtuce and seasoned breadcrumbs. Andrew Van Stee of Hearth is contributing Moroccan pistachio carrot rolls, while Miles Odell of Odell’s Bagel is pairing dry-aged ocean trout with a coconut pea puree. Justin Fulton of Margot is preparing charred cucumbers with agretti, coconut broth and yuzu kosho, and Rema Maaliki and Harrison Porter of Bear Leek are bringing braised leeks with leek soubise, albufera and crispy leeks. The lineup also features plates from James Beard chef finalist José Avila of La Diabla, JohnDavid Wright of Rougarou and pastry work by Ali Spahr of Hearth .

The actual preparation happens entirely outdoors. The chefs arrive early in the morning to set up tables, tents and their own Japanese konro grills packed with binchotan charcoal.

“It all happens out in the field, in the middle of Mark’s gardens,” Freeman said. “We set up that morning. We’ll set up the tables, the tents, everything. Then we do all the cooking in front of everyone.”

Diners can stand right by the workspace and watch the dishes come together. For the chefs, the open-air format offers a rare chance to step away from their respective restaurant kitchens and collaborate directly with their fellows.

“For us, as chefs, we just don’t get to see each other very often, so it’s really fun and special when we do,” Porytko said. “We definitely have our own little hangout in the kitchen area with all the chefs, you know — all the weirdos in the corner.”

Freeman echoed the sentiment, noting the benefit of the format for the guests as well.

“With this one, you’re getting 10 different chefs with 10 different views all coming together under one roof,” Freeman said.

Cooking in an open field does, however, mean operating at the whim of Colorado’s summer elements. Freeman recalled a previous year when a sudden onset of mountain weather forced the culinary crew to quickly shift from grilling to structural defense.

“The first year we had a little bit of rain at the start of it,” Freeman said. “Then the wind was crazy, where we all had to come and grab the tent so it didn’t blow away.”

Hopefully, on Sunday, the weather will remain tame, but guests should prepare for whatever Mother Nature has to throw at them, just in case.

The event takes place on Sunday, with arrival at 5 p.m. and dinner at 6 p.m. The location is Esoterra Culinary Garden, 8985 Valmont Road, Boulder. Tickets start at $260 and are available through Tock.
