Like all Shake Shack burgers, this one begins with a Martin's potato roll, which is single-handedly responsible for the creation of the word "squishy." The beef itself is a four-ounce patty that's smashed onto the griddle to achieve a caramelized lace on one side. The restaurant uses a hormone- and antibiotic-free blend of Angus sirloin, brisket and short rib.
The regional magic happens with a topper of marinated green chiles, jalapeños and scallions. This isn't the standard roasted green chile we're used to out here in the West; it's more of a crunchy relish, only without any sweetness. There's also a sprinkle of shredded white cheddar, which takes the place of the standard square of American cheese. It's a fun burger with a fresh, barely spicy edge, so it's worth ordering at least once for the novelty factor, if nothing else (for you Shake Shack special-menu completists). But we're guessing it won't replace what fans have been salivating over since the news broke last year that the burger joint would soon arrive.
If you plan on braving the line come Wednesday (the doors will open at 11 a.m. after a 10:45 ribbon-cutting ceremony), make sure you leave room for dessert. The frozen-custard concrete made with a slice of salted honey-lavender pie from Denver's own Long I Pie (a true artisan original from Shauna Lott, who bakes her pies in cast-iron pans) is insanely good. Or go with another locally made confection: a concrete with a Glazed & Confuzed doughnut blended in. Doughnut and pie flavors will change regularly, so there will always be something new to look forward to on the menu.
