I was raised in a Slovak family and pierogies were a staple of the diet. My mom would spend hours and hours making them and my brothers and sister would absolutely demolish all of them in one sitting.
I remember four types: Lecvar, sauerkraut, cheese/potato and cottage cheese, dripping in butter with chopped sauteed onions. Um um good.
My Mother, who was Slovak, would also make us a dish here or there that was Slovak, but I never learned the Slovak names. One Slovak dish was a ground beef and onions concoction and I wish I could remember the name...we also had a strong Polish influence in the foods my Mother served, and the two food influences were simply delicious and so memorable.
