Cabbage is at its best when it's in season in the late fall and winter months, but it stores well and can be enjoyed year-round. Whole heads of cabbage will stay fresh for several weeks in a fridge, but once they're cut, they need to be used up within four to five days. If it's not cabbage season and you can't find it organically grown, I always recommend rinsing it in a basin of cold water with about 1/4 cup apple cider vinegar to remove any pesticide residue, especially if eating it raw in salads and coleslaw.
The main varieties of cabbage are green, red and Savoy cabbage, with bok choy, Chinese or Napa cabbage, kale and brussels sprouts also being members of the same brassica family. The outer leaves in green cabbage are exposed to light, which develops the chlorophyll, hence the deeper green color, whereas the inner leaves are a paler color with a crispier texture and are often referred to as white cabbage—my favorite for making my crispy slaw!
