I never had perogies when I was young... I was at one of my high school friends back in the day that were Polish and they had some perogies and I tried them....
My mom is 1/4 Polish and one time I asked her, "Why didn't we ever have perogies - we're Polish??? Why do I have to find out about Polish food from my friends???"
She replied that she never had them either... I guess it's because they have been in this country for 4 generations and have gotten away from some of the old customs... So I bought some and took them to her house and we cooked them and she liked them....
