Blue Collar, by way of quick background, is a casual comfort food kind of place run by Chef Daniel Serfer, a Chef Allen alum. Opened around the beginning of the year, it's tucked into the small nook in the Biscayne Inn that used to house the now-defunct American Noodle Bar. I've not written about it yet but have been in several times.
Blue Collar's burger creations thus far have included the Chowfather Burger, topped with their "Big Ragout," latkes, bacon and a fried egg, the Fat Girl Hedonist Burger with chorizo, fried shallots, smoked gouda and chipotle mayo, and the Food-E Burger (a/k/a the Breakfast Burger), with Canadian bacon, an egg, maple mustard, and a side of cheese grits.
Now, behold the Frod Burger:
My particular version was loosely inspired by the outstanding burger served at Le Pigeon in Portland, Oregon. It includes slow-cooked, golden, caramelized onions, sharp cheddar cheese, an iceberg lettuce "slaw," and a smear of a a ruddy piquillo pepper aioli for good measure.
All of Blue Collar's burgers use a patty fashioned from prime dry-aged NY strip, a pretty luxurious grind for a pretty casual place. They also now all come housed in a "Portugese muffin," which may be a close to perfect vehicle for a burger. It's like the love child of an English muffin and brioche, tender but still having enough heft to hold up to a juicy burger, while not taking up nearly as much space as a brioche bun and distracting from the burger itself. Chef Serfer was awfully excited to get these in, and after trying it, I can begin to understand.
For a side dish, I asked Chef Serfer to take a shot at papas arrugadas, a dish I discovered at José Andrés' Jaleo restaurant in Washington DC. There he uses tiny marble-sized baby potatoes that are cooked in heavily salted water which crusts their wrinkled skins, served with mojo verde and mojo rojo sauces for dipping. Blue Collar's version uses a couple different kinds of little fingerlings, tossed in a slightly chunkier sauce with a good shot of herbs and vinegar to cut the richness of that burger.
I may be a little biased, but I think it's a pretty decent burger. Try it all week at:
