( 24-36 dumplings, depending on size)
I grew up in Edmonton which had a large Ukrainian community, and learned to make these when I was still a teenager. Pierogi were serious business; a friend's mum once wrote me a "sick note" so I could skip an afternoon of school to help her make a huge batch, lol.
These dumplings are usually boiled, then coated with butter and served with fried onions and /or crispy bacon bits and sour cream.
They come with a variety of fillings. The popular one in Edmonton contained mashed potatoes and sharp cheddar cheese. Others were filled with sauerkraut or meat, and then there were the dessert pierogi filled with cherries, blueberries, saskatoon berries or plums.
For the New Year there were tiny ones filled with mushrooms which were placed into soup bowls with hot borscht ladled over them. My mouth waters just thinking of those.
I double this recipe and freeze most of the ones I make. Just place them on a lightly floured cookie sheet after they are filled and place them in the freezer for about 15 minutes. At that point you can bag them for further freezing. When you are ready for the frozen ones, just drop them straight into the boiling water; don't defrost them.
