My husband found these at our local Dillon/Kroger grocery store. I wondered about pronouncing this word so I read the fine print on the side of the box. It seems that the word is Polish and the way to say it is: punch key. In Austria they are called Krapfen and in Germany, Berliner. That makes me think of John F. Kennedy's speech at the Berlin wall when he said, "Ich bin ein Berliner." This actually states in the German language, "I am a jelly doughnut." An obscure mistake in a language that has many wonderful idiosyncrasies!
By the way, the Paczkis are very good.
