I beg to differ with you asuchy, but the Prasky, as you know it, is definitely not a "Polish-American" thing, it's "Czech-American", and mainly a Midwestern one at that.
The word "Prasky" is an American twist on the Czech word "Praski" which is slang for "Pražská", which translates to "Prague, the capitol city of the Czech Republic. Throughout the city, there are hundreds, if not thousands, of food stands bearing the sign "Pražská Klobása", or "Prague Sausage". In short, it's simple, straight forward street food, kind of like hot dog stands in some American cities such as New York City, Chicago, etc. All taste pretty similar, but with their individual subtle variations. As such, I doubt that a single defining formulation for the sausage exist.
The meat component is typically coarsely ground beef and pork with the heavy emphasis leaning on the pork. I've heard of ratios being of 70%/30% or 80%/20% for the pork to beef ratio, but I can't confirm that. Beyond that, garlic is a defining ingredient, but in various quantities depending upon the maker. In addition to salt and ground pepper (black or white), spices such as caraway, as well as paprika, are often included. To a much lesser degree, marjoram is sometimes substituted for the caraway.
The introduction of Praski to America is generally attributed to a small group of Czechs who immigrated to America in the 1920s, and settled on the South side of Chicago. Wanting to replicate the sausages that they loved in their home land, they developed a formulation for Praski, as well as some other Eastern European ethnic sausages, and founded a small processing company known as Crawford sausage Company. Their products were, and still are, marketed under the name "Daisy Brand" as in the term of their motto, "As fresh as a daisy."
The popularity of Crawford's Praski grew rapidly and other local immigrant sausage makers such as Bobak's, etc. started selling their own version of the sausage. Over time, the popularity spread to other areas in the Midwest and local makers responded with their
Thank you for the schooling, I appreciate it! I am part Czech so that is great to know. I am close to Cleveland and my dad grew up there. He remembers local butchers having their own unique versions of it like you said. Sadly those days are gone. Most butchers left don't offer very many unique recipes. That is why daisy and boback are among the few that produce it. As a chef I want to try to bring back old ways and recipes. I am experimenting right now with a batch. So far the test tastes good. The only way to know for sure is after it is all cooked and rests. I will post my recipe in the next day as soon as it's finished!
