What kind of cabbage can I use to make sauerkraut?
You can use any kind of cabbage to make sauerkraut: green, red, savoy, Napa or any other variety and in any combination.
Since different varieties of cabbage have different colors, flavors and textures, the resulting sauerkraut will reflect that. For example, Savoy cabbage is firm, so a sauerkraut made with it will hold together more than a sauerkraut made with Napa cabbage, which is softer. A combination of red and green cabbage will lend your sauerkraut a pink hue.
If you like, you can even toss in vegetables like carrots and Brussels sprouts, and aromatics like onions and garlic for different flavor combinations. The possiblities are endless.
