I use 2% salt and ferment as close to 65 degrees F as possible.
For the best texture and flavor, slice parallel with the point of the quarter, the same way lumber is quarter-sawn. The best thickness is just 1mm. Doing it as described exposes the most cells, which leads to better fermentation, which then leads to better flavor and texture.
I don't like to pound the kraut the way that some do, it's bad for the texture, rather, I salt it and place it in the fridge overnight to soften up some and release water, I them pack it tightly but gently in the fermentation container eliminating any air.
I usually prefer plain kraut, but I do occasionally add juniper berries and/or caraway seeds.
