These days, since hubby doesn't eat red meat, I only buy chicken & turkey sausages. Luckily, the different types/flavors available are staggering. Some favorites are "Artichoke & Garlic", "Chorizo", "Andouille", "Cilantro & Chili", "Basil & SunDried Tomato", "Spinach & Feta Cheese", "Italian Cheese", "Hot Italian", "Sweet Italian" - the list truly is virtually endless. And they're all SO GOOD!!
For myself alone, my favorite sausage would have to be "Jeternice", which is a Czech liver & grain (usually rice or barley) sausage. It was usually served with another Czech sausage - "Jelitzy" - which is a blood & barley sausage. The Jeternice was always my favorite though. Traditionally served in my family with Czech bread dumplings & sauerkraut.
I haven't enjoyed it in over 30 years, but did just find a Chicago sausage maker that ships it & absolutely positively MADE my elderly parents' Xmas by sending them 5 pounds of each. My dad was practically crying over the phone he was so happy.
