Rind

Definition

 * 1) The protective external surface of a cheese. Rinds can be natural or artificially created, thick or thin, hard or soft, washed, oiled, brushed or paraffined. Their prime role is to protect the cheese's interior and allow it to ripen and develop harmoniously. Their presence affects the final flavour of the interior of the cheese.
 * 2) The peel of citrus fruits.
