I found the alleged article that was published by a DPRK newspaper on 12/22/2021. As far as I can tell it only says that Kim Jong Il liked meat filled wheat buns.

At Stall for Wheat Cakes Stuffed with Meat

There can be seen at a stall the people having wheat cakes stuffed with meat and saleswomen kindly expounding to the customers on the nutrition value. This harmonized scene adds luster to its popularity.
Whenever we witness such scenes we recollect with deep emotion the image of Chairman Kim Jong Il being pleased during his field guidance to the newly built workshop at the Kumsong Foodstuff Factory.
When the Chairman dropped in at a mobile service stand he instructed that they should serve people the stuffed wheat cakes warmed up.
Still we recollect his words saying our people would be more delightful to be served mineral water in summer while hot tea in winter with wheat cakes at stalls.
The respected General Secretary Kim Jong Un, who has succeeded to the history of noble love for people of the Chairman, took meticulous interest in the wheat cakes ranging from its production to service and took measures for it.
Indeed, a small stall for stuffed wheat cakes is associated with the motherly love of our Party.
