All of our delicious pierogi are made by hand in house and are pre-boiled. There is no need to boil first (unless that's how you fancy them!), they can go straight to the pan frozen. There are 5 different reheating instructions on the back of every package. They each measure about 3" across and are larger than the average pierogi. That's how our Babcia made them for us, so that's how we make them for you!
