As requested by Macabre, here is my family's recipe for perogy dough, which also happens to be the same recipe we use to make noodles for in soups and stuff.
~240g/~2 cups unbleached flour
1 g/1 ml/¼ teaspoon salt
4 g/5 ml/1 teaspoon baking powder (for noodles only, not perogies!! - completely optional, however)
125 ml/½ cup soy milk (water will work too but soy milk is better, or whatever type of milk is safe)
~50 ml/~¼ cup water
In a large bowl, whisk together the flour, salt and baking powder (if using).
Add the soy milk and water and stir until a thick dough forms. Knead the dough into a ball.
Let the dough rest for 20-30 minutes.
Roll out dough to desired thickness and cut into desired shapes.
My husband likes thicker dough and rolls it by hand. I prefer to use a pasta roller and let it do the hard work; the thickness is more consistent that way too.
To make perogies:
Roll dough fairly thin.
Cut into squares about the size of the palm of your hand, or a little bigger. (Or cut in circles)
Add about a teaspoon of filling (we use plain mashed sweet potato) to the centre of each piece of dough.
Fold the dough in half, pinching the edges to seal. Brush on a little water if the dough is too dry to stick to itself.
Leave the pirogies out on a cooling rack for several hours until the dough is dry. You may have to flip them once.
Where we used to live, that was only a few hours, but where we live now it takes almost a day until they aren't sticky any more.
Transfer the perogies to a cookie sheet and freeze for 4 - 6 hours before placing them in a storage container - this prevents them from sticking to each other.
Cook perogies in boiling water for 8-10 minutes (Approximately, I never actually cook them; my husband does and couldn't tell me how long they boil for.)
To make noodles:
Roll the dough to your desired thickness. My husband likes really fat noodles but I like them thinner. Cut them in desired shapes. Cook them in bolding water until they float and puff up a little. Again, I'm not really sure how long it takes, but 8-10 minutes should be enough. You can always taste test them for doneness.
