Tips and Storage: Rutabaga skin is edible, but it might have a stronger flavor, so peeling is recommended but not necessary. However, if you purchased rutabaga at a grocery store, it’s most likely covered in wax and will require peeling.   Why are they waxed? With a higher moisture content than other root vegetables, rutabaga are prone to dehydration and are often wax coated to prevent deterioration.  Store unwashed, tops removed. If unwaxed, store wrapped in a damp cloth or paper towel in a ventilated bag in crisper drawer of refrigerator.
