Pop-ups are everywhere in New Orleans. They’re at neighborhood festivals and markets, they’re in the back kitchens at corner bars and they take over other restaurants for one-off appearances or weekly gigs.

Next Wednesday, a richly diverse cross-section of the city’s pop-up food economy will be gathered under one roof.

The event is called Propeller Pop, and it’s an annual fundraiser for the nonprofit Propeller. Through its business accelerator program, Propeller helps local entrepreneurs launch new nonprofit and commercial ventures in fields like education and youth development, public health, water management and access to healthy foods.

Propeller Pop is held at the group’s Broadmoor headquarters to spotlight their work, and each year Propeller invites a different collection of pop-ups to provide the food. Along the way, the event has grown into an annual showcase of new flavors and different paths for up-and-coming chefs and food entrepreneurs.

“Pop-ups are in many ways the start-ups of the food world now,” said Catherine Gans, the Propeller’s marketing manager. “That’s the connection between what they’re doing and what we do.”

This year, Propeller Pop marks the nonprofit’s own fifth anniversary and a milestone of 100 businesses launched with its support. The pop-ups taking part are as varied as ever. Some are well-known, like the prolific pop-up the Old Portage, which has regular gigs at venues across town, or Milkfish, which is back in pop-up mode after running its own Mid-City restaurant for a stretch.

Three others – the PDR, the Sweet Spot and Koreole- are just coming off stints at St. Roch Market, the food court on St. Claude Avenue and are now working on their own (the Sweet Spot has just established a new home base, with a stand at the French Market). Others are just getting started, and some have big plans ahead.

At Propeller Pop you can sample and check in with each. Drinks are also provided in the pay-one-price admission, including Abita beer, wine, a spiked version of mango freeze and a signature cocktail from Kevin Augustine of Cochon Butcher (garnished with Pop Rocks, naturally).
