Quite often there is a heavy layer of paraffin wax on the skin. I really don't like the idea of ingesting that. I never have a problem peeling turnips or rutabagas. I cut them in half from pole to pole. Then in half inch slices and peel. Just under the skin is a very light layer in color. Only about 1/8" wide. You should peel that layer off. It is very bitter and often the reason a lot of folks do not like turnip.
