I note that you wrote that Yapchik is a recently invented or contrived food dish. I am sorry to be the one to correct you. My mother, a Holocaust Survivor from Lodz, Poland, made this dish when I was a child throughout the 1960s and right up until her death in 1995. She definitely spoke of it as a common dish that was prepared during her childhood in pre-war Poland. Although she referred to it as Cholent or Choolent. I have since learned that what my mother really made was a Yaptsok or Yapchik. I actually heard it referred to as a “Yaptsok” by a Polish Jew when I was about 8 years old. In any case, my point is that this is a dish that is probably more than 100 years old, and is far from a recent concoction/recipe, given that my mother was born in 1920.
