A kosher food grocer found himself in a sticky situation when 10 bags of weed — stashed inside vacuum-sealed bags of peanut butter — showed up at his Brooklyn shop in the mail, police sources said.

The owner Kahan’s Superette told cops whoever mailed the mystery package must have made a mistake — because he doesn’t sell those kind of treats, the sources said.

“It wasn’t anything that they asked for,” a police source said.

The bizarre package arrived at the food market on Kingston Avenue near Union Street in Crown Heights at 4 p.m. on Monday, the police sources said.

“Wrong delivery address results in the seizure of 10 large bags of marijuana wrapped in peanut butter,” the 71st Precinct tweeted, along with a photo of the gooey mess on Monday.

The marijuana, which was delivered by the USPS, was wrapped in plastic bags then covered in peanut butter.

“I have no idea where it came from. It was just dropped off,” a worker at the shop told The Post.

It’s unclear how much weed was in the packages. Cops declined comment on where the packages had been mailed from.

The grocery store sells such items as Marvid kosher chicken, bagels and fresh salmon, according to its Facebook page.
