My parents grew up in Baltimore city, Dad born 1917 and Mom 1922. My mothers family was a huge mass of Irish folks who may have arrived in the 1860's, My Dads's father was from Dublin......Baltimore City was a hodgepodge of ethnic cultures..Greek Neighborhoods, Polish, German, Irish, Italian as well as many Catholic, Episcopalian, Lutheran Churches and Temples. They had access to diverse market places, and the food was wonderful. The children my parents are up with from all the neighborhoods attended the same Catholic or public schools. So the kids played together, they were in and out of each others homes. I'm talking blue collar families, that attended each others weddings, bar mitzvahs, baptisms and wakes.
So all the food terms were homogenized so the different native speakers would understand. Smearcase is Baltimorese for schmierkasn.. We learned early what a good cruller should taste like, how to know when pierogies are authentic, also Moussaka, Souvlaki, my Grandmothers Corned Beef and cabbage, sauerbraten and dumplings.........far too many to remember. Back then the terms were homogenized.....now the food had been dumbed down.
