Well, Swedish pancakes are not crepes, but the are served as such here, and they do resemble crepes more than “American Pancakes,” so when trying to describe them, the path of least resistance is “crepes” to let the conversation move forward.
Potatiskorv (Potatoe Sausage) is not as unknown as people try to imply. However, it is more of a dish on the Swedish X-mas table (a version of a smorgasbord or buffe) these days. Another trend is of course that the Swedes, like any other people in the western hemisphere, are working more and eating out in greater scale, and in the restaurants or fast food joint (McD’s BK, Subway, etc), you will be hard pressed to find anything but traditional fast food.
With that being said, I’m not sure how a Swede living in Sweden doesn’t know what potatiskorv IS. It would be like saying that one doesn’t know or have heard of chicken and dumplings, red beans and rice, black eye peas, or grits for an American. It’s not something I eat, even rarely because of choice, nor is it served in the area I live in any larger capacity, but I certainly know what it is and how to get a hold of it if I wanted to.
To answer the original question.
Potatoe Sausage can be served with boiled or mashed potatoes. Sauerkraut or pickled red cabbage is also associated with this type of sausage. If you choose to give a quick browning, for texture and taste, after you’ve boiled it, you can dice up some cold, boiled potatoes and fry that up (like home made hash). Swedes also used to like their “brown beans” (beans that had been soaked and then boiled with a little bit of syrup, vinegar, and a few other spices). I would also venture to guess that those worried about carbs could steam some cauliflower, broccoli, green peas, and add a few pickled red beats (or red cabbage) on the side for color. However, the most frequent sightings of potatoe sausage these days is as a part of the Swedish “Julbord,” and at that point, the sausages are just served by themselves in on a serving tray for people to pick if they want.
As with most Swedish food (Husmanskost), you’re not going to go wrong with a slightly chilled beer (in this case I would recommend a lighter beer), milk, or water. Because of the possible inclusion of pickled veggies, I would stay away from sweet drinks, such as soda pops, as the contrast would be a bit much.
All this IMHO, of course!
