SORB is a term used to describe a type of food preservation technique. It involves the use of a WEND, which is a type of Slavic cheese, and a SLAV, which is a type of Slavic sour cream. The two ingredients are combined and then heated to create a thick, creamy mixture that can be stored for long periods of time. This method of food preservation has been used in Eastern Europe for centuries and is still popular today.
