The powers that pop have decreed that Monday is National Popcorn Day. Though the origins of the “holiday” are unclear, here are three ways to celebrate it in D.C.

Popcorn Queens: This mother-daughter duo sells bags and buckets of gourmet caramel popcorn in flavors like classic caramel, peanut, chipotle, cinnamon-apple, bourbon pecan and Chesapeake, made with Old Bay. “We wanted to pay homage to the area,” says co-founder April Wardlaw.

Stella*s PopKern: D.C.’s first gourmet popcorn food truck, Stella’s serves GMO-free kernels curbside in flavors like butter with sea salt, white cheddar with Old Bay, and chocolate drizzle with sea salt. Truck operations are suspended for winter, but in the meantime you can find tins online.

Popped! Republic: This D.C. food truck with a storefront in Alexandria offers hot air-popped and “wet” kernels popped in corn or coconut oil. Highlights include K Street Kettle Corn, White House White Cheddar and the Obama Mix, right.   2381 S. Dove St., Alexandria;
