Storage
When stored properly, they retain good taste and high quality.
Whether you buy a small cellophane package of shelled pecans or a five-pound bag of in-shell pecans, the best place to store them is in the freezer. Pecans can spoil quickly under warm temperatures, but will keep fresh one year at 32 degrees Fahrenheit.
Pecans do not have to be thawed before being added to a recipe. Even if they are not part of a cooked dish, they will thaw adequately before serving. Also, portions unused can be returned to the freezer without any loss of quality. During the holiday season, keep the pecans refrigerated—even in-shell—until they are ready to be served.
