There’s a lot of regional debate about what should and shouldn’t go on a hot dog. In Chicago, they never use ketchup, but they do put tomatoes and pickled peppers on their dogs. On any street corner in New York City, your dog is probably going to have yellow mustard and steamed onions. There’s even an old tradition in my beloved Philadelphia that puts fish cakes on a dog. For me, all dogs are created equal, but my favorite topping—and, perhaps, the most iconic—is sauerkraut. But what is sauerkraut, really? I’m about to tell you all about it.
What is sauerkraut?
Sauerkraut is a condiment/side dish hybrid made of finely chopped, fermented cabbage. Americans most often associate it with German cuisine—and rightfully so, it is a national dish of Germany—but many Central and Eastern European countries have their own sauerkraut varieties, including Poland, Russia, Ukraine, Austria, Slovakia, and Czechia, to name a few.
Sauerkraut often accompanies meat dishes like bratwurst, or is used on Reuben sandwiches or the aforementioned hot dog. It’s also very popular with pierogies (with a dollop of sour cream; if you know, you know). Some places will mix it into mashed potatoes or mayo-based salads. Or, we have a few ideas of our own on what to eat with sauerkraut.
What does sauerkraut taste like?
The taste is in the name, even if it’s spelled the German way. Good sauerkraut has a sour punch, backed by acidic and salty notes. It’s not sour like Sour Patch Kids or Warheads; it has a far more natural taste (close to the flavor of a pickle) that is quite delicious in big heaping doses.
Is sauerkraut fermented?
Yep, and it’s the good kind of fermentation, not the “clothes left in your gym bag” kind.
How is sauerkraut made?
Sauerkraut is made with three simple ingredients: cabbage, salt, and time—not the herb, thyme, but the arbitrary unit of measure that we’ve collectively agreed on as a society.
To make sauerkraut, finally chop cabbage into strips and then pack with salt. After letting it all sit for a half hour, mash the cabbage in order to extract the water. Put the whole shebang into a container and press down so that the water rises above the top of the cabbage. Seal the container and then wait—the longer you let the cabbage sit, the more “sauer” it becomes.
Why is that? It’s because of that fermentation we talked about. Bacteria eat the natural sugars in the cabbage, creating lactic acid which accounts for the sourness. At minimum, the fermentation process should last a week. If you simply can’t wait that long, there are plenty of pre-packaged sauerkraut options in your grocery.
How long does sauerkraut last?
Sauerkraut can last for four to six months in the refrigerator. Compare that to other pickled vegetables, which usually only last four to six weeks. You get a lot of mileage out of your kraut!
Can you freeze sauerkraut?
Yes you can freeze sauerkraut, as long as you make sure that the container is sealed tight to prevent freezer burn. Also, just a heads up: Freezing for a long time can negatively impact the flavor and consistency of sauerkraut while also destroying potential probiotic bacterial elements that are touted as healthy.
Is sauerkraut probiotic?
It is! The bacteria that creates the fermentation is called lactobacillus, which is a major part of our gut biomes. So not only does sauerkraut taste good, it’s good for you. Apply liberally to your next dog!
Is sauerkraut keto?
Sauerkraut is keto friendly! A cup of kraut has only 2 grams of carbs. So, if you’re tired of choking down plain ol’ turkey burgers, you can feel confident adding this condiment.
How do you eat sauerkraut?
I, for one, suggest utensils. But if you simply must shovel fistfuls of sauerkraut into your mouth, I won’t stop you. But I may snap a picture while you do it.
No. I mean what do you eat with sauerkraut?
Oh, silly me. Well, besides the obvious hot dog, sauerkraut is a common side dish in many Central and East European cuisines. Here’s my dream plate: pork schnitzel, spaetzle, roasted potatoes, cucumber dill salad, and a heaping pile of sauerkraut. Or, replace the schnitzel with a variety of wursts.
If you go to any semi-respectable Jewish deli, you simply must get a Reuben sandwich piled high with corned beef and kraut. I’ve also had pierogies and, in place of fried onions, substituted sauerkraut and it was pretty nice. Get creative.
Where do you find sauerkraut at the grocery store?
That depends. You can find canned or jarred sauerkraut in the same aisle with all the canned vegetables and baked beans or you might find it in the pickle aisle. But eating sauerkraut out of a can just doesn’t seem right. My opinion is to head straight to your grocery store’s refrigerated aisle. There, you can often find sauerkraut cold and ready to go. That just seems like the fresher option to me.
