Once fully cooled, Springerle must be stored in airtight containers, where they will keep for months. Do not eat them right away; they need time to develop their flavor and, more important, their texture. When they are freshly made, in the first few weeks or so, they will be crunchy on the outside but, when pressed, their crust will shatter slightly, giving way to a soft interior. As time goes on, they will get harder and harder, eventually getting so hard that you’ll be able to eat them only after dunking them in hot tea. I prefer Springerle when they get this hard, but others prefer to keep them soft. To do so, store the cookies with a piece of bread or a chunk of apple, which will supply them with moisture and keep them soft (replace the bread or apple every few days) .
Most butchers will remove the backbone for you.
