Styrian Sour Soup (Štajerska kisla juha)

Štajerska kisla juha is a traditional sour soup originating from Lower Styria. It’s usually made with a combination of pig’s trotters, pork head, garlic, onions, salt, pepper, marjoram, parsley, thyme, apple or wine vinegar, potatoes, sour cream, and flour.

The meat and vegetables are sliced and boiled in water, then mixed with a combination of flour and sour cream in order for the soup to thicken. At the end, vinegar is added to the soup to make it more sour. This soup is traditionally prepared during pig slaughter, known as koline, and it was typically served after midnight.
