I preserve more herbs and other foods in salt than in sugar, but if you have a sweet tooth, you might do the reverse. As I explain this week in my Twice as Tasty column for the Flathead Beacon, sugar, like salt, absorbs moisture and oils and inhibits spoilage. In high concentrations, such as in jams made without pectin, sugar traps enough water that microorganisms can’t grow. Once unsealed and refrigerated, such jams last longer than low-sugar jams, and mold usually forms only on the surface and only after weeks of air exposure.

As sugar absorbs natural oils from herbs and spices, it also picks up their flavor. Vanilla sugar is a simple example—and a fantastic way to repurpose a vanilla bean pod once you’ve scraped out the seeds for jam, buttercream, or a sweet sauce. You get the same effect when you infuse sugar with herbs, edible flowers, and other botanicals. You can use these in any recipe that calls for sugar, but they have the most impact when used to sweeten whipped cream or frosting, sprinkled on baked goods, baked into simple ones like shortbread, or stirred into a beverage.
