Potatoe and Cheese Pierogi
Ruskie Pierogi are probably the best known pierogi. They are very simple to make but with a distinct taste. Whether they are Russian or not, as the name possibly implies, is unknown as there are many different stories why they have their name.
You can also freeze the pierogi. You can either boil first or freeze raw. Lay on a cookie sheet without touching until frozen, then place in plastic bags.
Note: If Farmers Cheese is unavailable, then dry Ricotta cheese may be also used but you should season it stronger to make up for the flavor difference.
