The Art of the Perfect Truffle Fry at DMK Burger Bar
“You’re going to have a gourmet burger joint, you better serve up a gourmet fry,” Guy declared after tasting what might be one of the most meticulously crafted french fries in Chicago. About eight blocks south of Wrigley Field on Sheffield Avenue—the same street where baseball fans scramble for home run balls—DMK Burger Bar is proving that side dishes deserve just as much attention as the main event.
Building an Emulsion from Scratch
Head chef Michael Cornick walked Guy through the process of making their signature truffle aioli, and it’s anything but a shortcut operation. They start with egg yolks and get the emulsion running with just a bit of lemon juice before slowly incorporating virgin olive oil. The magic ingredient? White truffle oil—and as Cornick noted, “you’ll smell it as soon as it hits the bowl.” A touch of salt, pepper, and more lemon finishes it off. DMK makes a big batch every three days, and yes, they do it by hand.
The Science Behind a Crispy-Yet-Tender Fry
What sets DMK’s fries apart isn’t just the truffle aioli—it’s the obsessive attention to potato selection and technique. Cornick explained that they specifically source well-aged Idaho russet potatoes that have been stored for three to four months minimum. Why? “When we don’t have that, we end up getting fries that cook too fast, brown up too fast because you’re burning the sugars, and the fries not really cooked.” It simply doesn’t work.

The potatoes go through a french fry cutter at 3/8 inch, get washed and drained, then hit three different fryers. The first stop: blanching in beef fat at 250 degrees for about four minutes. After resting on a tray, they’re finished in beef fat for another three minutes until golden brown. The team handles them delicately with tongs—”when they’re this soft they can break into a lot of little pieces,” Cornick warned.
While still slightly wet from the fryer, the fries get seasoned with salt, pepper, a generous hit of Parmesan cheese, and parsley for color. Served with that house-made truffle cream on the side, this is no ordinary basket of fries.
Guy’s Verdict
Guy didn’t hold back on his reaction: “Crunchy exterior, tender, such a richness.” He appreciated the skin-on approach and loved the pepper—”I like pepper on my fries too.” But what really got him was how the aioli worked with everything else. “It melts right into the fries. I mean, real deal, man. Real deal.” He called them an “excellent truffle fry.”
The customer testimonials echoed the enthusiasm, describing them as “crispy but soft in the middle, real potato taste” with truffle that’s “delicious” and cream that’s “kind of sweet,” creating a “very rich taste” balanced by the tangy Parmesan on top.
Tips from the DMK Kitchen
Age your potatoes: Fresh isn’t always better. Well-aged potatoes (3-4 months) have converted their sugars properly, preventing premature browning and ensuring the interior cooks through.
Double-fry in beef fat: A low-temperature blanch followed by a higher-temp finish creates that ideal crispy-outside, tender-inside texture.
Season while wet: Adding salt, pepper, and cheese immediately after frying—while the fries still have surface moisture—ensures the seasonings actually stick.
