Pickled Sausage 

They are still made and sold.

I get it at the local grocery store I like the harvest double smoked farmers sausage

Hello it is the pickling spice

Hello a couple days and they are ready to go 👍

Hello No I don’t 😊👍

You never remove the casing from cooked sausage plus all cooked and smoked sausage contain instacure #1 to prevent bacterial spoilage. However, raw sausage like bratwurst must be refrigerated prior to use or cooking.

Those sausages are already fully cooked. The vinegar will help to preserve them but I wouldn't leave them out for too long. Not knowing the pH of the brine after adding water plus the fat from the sausage may not be enough to make them shelf stable or unrefrigerated.

You can but I didn’t this time, we just ate them up lol

You really don’t need to sterilize the canning jars and lids because vinegar is glacial acidic acid that destroys bacteria
