I second the Polish Heritage Cookery by Robert Strobel. Great reference.
My friend's mom made a roast chicken and "kartoffle" every Sunday. It was an awesome dinner and I was always happy when they invited me to stay for dinner. Kartoffle are mased potatoes, but the best "mashed potatoes" ever!!! Anyone know how to make them?
Kartoffe is just the word for potato in central and eastern Poland. (not surprising that is also the same in German). My Polish husband's family generally just boils the potatoes, drains them and then mashes them with a hand masher. They think my American style of beating them with a mixer and adding milk and butter is just too much work. But they do like them my way for special occations.
