Chives are best preserved by freezing but can also be dried says VeggieHarvest.com. Although a supply of fresh chives is relatively easy to maintain, freezing or drying chives properly will preserve them for future use as a delicious substitute in many recipes.
To properly dry chives, tie the whole stems in small bunches and hang them upside-down in a warm, dry, dark place. Crush dried chives just before using for best flavor.
Flavor is also well preserved through other methods such as layering chives between measures of kosher salt in a class jar or preserving chives whole with the flower in a glass container of white vinegar to produce a pretty gift of lavender flavored vinegar.
