Although this is called 'russkie', it refers to Ruthenians, or Eastern Slavic people.The 500T flour refers to the grind, which is finer, like Italian 00 flour. You are looking for 11% protein plain/all purpose flour. It will say on the packet how much protein there is. I believe the higher the protein, the more gluten and stretchiness in the flour, which is what you want when making pierogi. Here is a great guide to Polish flour.

Instructions
For the dough:
Mix the flour and salt in a bowl
Mix the hot water and butter in another bowl, until the butter melts
Mix the dry and wet ingredients together, kneading until you have a shiny dough that doesn't stick but does form a clump. The amount of water is dependent on the weather and your kitchen so add water if it's too dry, tablespoon by tablespoon.
Cover with a damp tea towel and leave to rest for 30 minutes at least.
For the fried onions:
Slice up the onion finely and soften in a pan with the butter until golden. (This is so delicious you may want to do 2 onions).
For the russki stuffing:
Boil the potatoes in salted water, whole with their skins on. Once a fork goes in easily, after 15 to 20 minutes, remove and skin.
Using a ricer or a potato masher, mash the dry potatoes and mix with the twarog/cottage/quark cheese. Season with salt and white pepper.
You have a few options here: many readers swore by adding sauerkraut to the mixture. I put in dill which tasted great. You could also add fresh grated horseradish. Felicity Cloake added some of the fried onion to the mixture. Set aside your mixture and roll out the pierogi.
To roll out the pierogi:
Once the dough is rested, lightly flour a clean surface.
Using a rolling pin, try to roll out as large a piece of dough as possible, to a couple of millimetres thick. You can reuse scraps but the second batch of pierogi will be tougher, hence my advice to roll it out as big as you can, to get as many as possible from the first batch of dough.
Using either a glass or an 8/9cm circular pastry cutter, cut out the pierogi. Leave them on a floured tray or another section of kitchen counter, covering them again with a damp tea towel until you are ready to fill them.
Filling the pierogi:
Using a teaspoon, add a little of the mixture to the middle of each pierogi. Don't overstuff as the dough might break. The dough is quite dry, so have a glass of water to moisten your fingers to close them up into clam-like semi-circles. Store on the floured tray.
For the strawberry stuffing:
Another alternative stuffing is strawberries (or blueberries) simply cut up and put inside the pierogi. It's surprisingly delicious.
Cooking the pierogi:
Fill a wide saucepan with boiling salted water. If you are going to eat them straight away, have another pan with the butter for sautéing.
Pop half a dozen of the pierogi into the saucepan. Once they float, 2 or 3 minutes, fish them out with a slotted spoon and deposit them on another tray with either a silpat/silicone mat or grease proof paper. Don't let them touch each other. Keep doing this until they are all cooked.
If you want to eat them later, store them in the fridge, and sauté just before eating. They last 3 days. Or you can freeze them. If using immediately, sauté them in the pan with the melted butter.
To serve:
Put a few pierogi on each plate, top with sour cream, fried onions. Serve hot.
For the strawberry version, serve with sour cream and poppy seeds.
