But the potatoes aren't the only things fried in beef fat. A week ago, the shop debuted a new doughnut prepared that way, selling them for $2 each.
Naturally, they've quickly caught the attention of a few curious eaters, who've posted pictures of the sugar-dusted treats on Instagram.
"They're light and cake-y. A nice little crumble to them," wrote one.
While the item is a bit of an eyebrow-raiser, it's not unheard of to fry desserts in animal fats. In the past decade, bacon fat (and bacon as a topping) has become quite popular in cookies and cupcakes.
In fact, meats of all varieties have become a go-to for bakeries looking to put out a novelty treat.
Many doughnut shops sell doughnuts topped with bacon, which are most often served with a maple glaze.
A few shops, like Sugar Shack Donuts in Arlington, Virginia and Gourdough's in Austin, Texas, offer doughnuts topped with chunks of fried chicken.
And then there are the restaurants that used two doughnuts as a bun for sandwiches, from cheeseburgers to bacon, egg, and cheeses.
