In my classes, I get asked a lot about the best way to store expensive raw food ingredients for the best and longest shelf life. Here are some of the answers I give:
Nuts, Seeds and Grains are best stored for between 3 months to one year in a glass jar in a cupboard or pantry. They stay even fresher stored in the refrigerator for up to a year or in the freezer even longer. The question becomes, how do you know how fresh they actually are and were they fresh when you bought them? If you buy your fresh nuts and seeds from a reputable source that has a high turn over such as Whole Foods, chances are pretty good that they are constantly refilling their bins and shelves with fresh ingredients. You can be sure you are getting something fresh there.
