Minted Simple Syrup
Wikipedia references Elizabeth Ortiz, "Harvesting of mint leaves can be done at any time. Fresh leaves should be used immediately or stored up to a few days in plastic bags in a refrigerator. Optionally, leaves can be frozen in ice cube trays. Dried mint leaves should be stored in an airtight container placed in a cool, dark, dry area." Ortiz, Elisabeth (1992).
