Pelmeni are basically Russian tortellini. But different. Does that make sense? The shape is essentially the same, and they are basically pasta, but the filling is different and they are served differently.
The standard pelmeni filling is ground meat (it can be a mix of beef, pork, lamb, my BF's mom even puts ground chicken in sometimes), onion, salt and pepper. I've never seen a different filling, and my BF looked at me like I was from another planet when I innocently asked, "Does anyone ever make pelmeni with minced fish inside?"
We made a bunch of them last night, it was a really satisfying meal.
PelmeniIngredients:2.5 glasses* of flour
1 egg
1/2 teaspoon salt
water as needed (approximately 1/2 a glass)
1/4 medium onion
325 g ground meat (I used beef, 20% fat)
salt and pepper
*A "glass" is a measurement used in many Russian recipes. I believe it comes from the time when most household items were very standardized; everyone had glasses of pretty much the same size and design. The glass I used was a cup in volume, and it's very close to the size of the magic glass referred to in Russian recipes.
Method:First prepare the dough. Place the flour and salt in a bowl, or if you're very awesome (which I'm not), on a clean dry surface, like a big wooden cutting board. Make a well in the center and add the egg. Start to mix, and add the water slowly, mixing as you go. You need to add enough such that you have a smooth, soft dough, but not too much or it will be sticky. If it gets a little too sticky, you can add extra flour, a little bit at a time. Knead the dough for a bit so it's supple and smooth.
Now prepare the filling. Mix the ground meat with chopped onion, add plenty of salt and pepper.
Roll out the dough very thinly on a floured large surface. Cut it into squares that are about 1.5" on each side. You can just use a "grid" method to do this, it's fast and efficient: make lines 1.5" apart going one direction, and then make them again in the direction 90 degrees away. Any pieces that are too small can be mixed together and re-rolled out.
Place a thimbleful of filling (about a teaspoon) on each square in the center. Now comes the tricky part, if you haven't done it before; the folding.

Above is my incredibly nerdy rendition of an unfolded pelmen. To fold one, first make a triangular pocket, bringing point D to point A, and pinching well to seal sides A/DB and A/DC.

Once you have a triangular pocket (poorly rendered above), bring points C and B together. You now have a finished pelmen. Repeat for the probably close to 100 squares you have!
This site has non-keyboard-generated pictures of the finished product, and of the preparation steps. They cut the dough into circles, which is also an option.
To cook them, bring lightly salted water or broth to a boil, and place them in the boiling water. Once they float, you can check the filling of one to see if it's ready. But I just let them all cook for a couple more minutes after they start to float, and then serve them.
Notes and Serving Suggestion: It's tedious. That's why this is usually a family activity, and I strongly encourage you to enlist help where you can. You can serve them in the water/broth they were cooked in, kind of as a soup. Otherwise, they can be eaten with butter, sour cream, vinegar, soy sauce, chopped greens on top, ketchup, whatever you want! My favorite is to put sour cream and chopped dill and parsely on them, eat them with the broth, or to eat them with soy sauce and apple cider vinegar.
