Unsalted means containing no added salt — the product is made without salt being put in during manufacture or cooking. Unsalted butter is the classic example: preferred by bakers because it lets them control exactly how much salt goes into a recipe, and by anyone watching sodium intake. Unsalted versions exist for stock, nuts, crackers, and preserved foods. The label does not mean sodium-free — foods naturally contain some sodium — only that none was added. Going unsalted changes flavour noticeably, since salt suppresses bitterness and enhances other tastes; cooks compensating with herbs, acids, and aromatics can make the absence a virtue rather than a lack.
