Oh, I do that, too! (The pierogi, I mean.) My dad is Russian-Polish and making them during the holidays gave me something to do that I enjoyed, while also keeping me out of the general family "togetherness" (which generally leads to yelling and annoyance.) Plus, pierogi! What do you fill yours with? I usually do potatoes and cheese, sauerkraut, and a completely non-traditional sautéed apples and cinnamon.
