Every Christmas we eat pierogi. When I was a child we ate pierogi throughout the year. My favorites were ruskie pierogi made with potatoes, cheese and onions and dessert pierogi filled with plums. Pierogi are part of vigilia the traditional Polish Christmas Eve festivities and when I lived in Chicago, with it's many Polish neighborhoods, it was so easy to buy pierogi that I never took the time to learn how to make them. Last year we spent Christmas in San Diego and finding pierogi involved a long trip through unfamiliar territory. Determined to avoid a repetition, I pulled out an old recipe of my mother's and decided to make my own.
