Salt and sugar get a bad rap for their effects on our bodies when consumed in large quantities, but their ability to act as a preservative is often underappreciated. Salt and sugar prevent spoilage and make it difficult or impossible for undesirable bacteria to grow. The rule of thumb for salt curing is that 20% salt keeps most undesirable bacteria at bay.

Although dehydrating and freezing are the most common ways to preserve herbs, the rising popularity of artesian salts and infusions has brought attention to herbs preserved in salt or sugar. The preservative pulls moisture from the herbs while keeping their flavor intact. Leaves plucked from the jar can be used as though they were fresh. The remaining herbed salt works best as the finishing touch, but infused sugar can also work within a recipe. A little of the flavored salt or sugar goes a long way, and the herbs keep a long time.
