What's the recipe for a food trend again? Ask Churro Borough [1], a Los Angeles churro pop-up, which may have nailed it with its churro ice cream sandwiches. First, you need a trained and inventive cook, like Sylvia Yoo, who has worked in some of the most respected restaurants in New York City (Jean-Georges and WD-50, anyone?). Secondly, take two beloved, iconic foods that are approachable and affordable: churros and ice cream, in this case.

From there, it's all about presenting the food hybrid in such a mind-blowing, never-before-seen way that Gen Y can't wait to gobble it up and tell their friends about it. Yoo pipes the churros into swirled disks and fills the fried dough with mouthwatering ice cream flavors: horchata, Mexican hot chocolate, and panna cotta, to name a few.

Next, it takes a journalist to instigate the mad dash. Though Churro Borough's ice cream sammies have been around since 2011, the wider world didn't catch on until this week. Chow [2] let its readers know that "churro ice cream sandwiches are happening in LA," and the Internet retweeted the heck out of it.

Lastly, crazes don't exist without a high demand. These frozen treats are only available via private catering events (but FYI, the team is experiencing a high volume of emails [3], so don't expect to hear back from them soon) and at local pop-ups and food festivals [4] like LA Street Food Fest on June 28 and Tasting Table Lobster Rumble on Aug. 1. Get 'em while they're hot cool, y'all.

Most importantly, a true innovator must always envision the next greatest thing. Be on the lookout for the release of these new items from the Churro Borough: ice cream shakes with churro dipping fries and churro-flavored macarons, aka Churrons. Because today's food trend is already yesterday's fad.
