I've only made one batch of potato sausage and I didn't even sample it. I made it for a customer who's wife was from Sweden and she longed for that sausage so I made him a batch from the recipe I had from the book I learned from and gave it to him in a Ziploc bag filled with water so the potatoes didn't turn brown.
He said she really enjoyed it---but I didn't see him again--:w
