A link of ring baloney, about a diameter thicker than a North American breakfast sausage, is pickled in a solution of white vinegar, white sugar, water, salt, and pickling spices. It is then either drained and sealed in plastic and sold, or coiled inside a large glass jar and sold still in the pickling solution. The jar sizes can be 1/2 gallon, 1 gallon or 5 gallons in volume.
Deli counters will stock the larger jars, which they’ll open and sell you a piece out of.
Pickled Baloney is more popular in the northern States of America, particularly Michigan.
You can make your own Pickled Boloney at home. Some people like to add sliced onion to their home versions for added flavour, and to make pickled onion at the same time.
The pickling solution, when the baloney is gone, can be used to make pickled eggs or pickled onion with.
