Things You'll Need
Sprouts, including bean sprouts, alfalfa sprouts and lentil sprouts, are newly sprouted seeds from grain or bean seeds. For the freshest sprouts, sprout your own, then store them in the refrigerator. If you've bought some, try to get them into the refrigerator as soon as you can. If you handle them properly, they should keep for a few weeks in the refrigerator. The most important thing you need to do is to make sure they're dry before you store them.
Rinse the sprouts well, then shake off the excess water.
Spread the sprouts on a double layer of paper towels and allow them to dry completely. Refrigerating your sprouts while they are still damp will shorten their shelf life.
Seal the dry sprouts in an airtight plastic container or produce bag. Place the bag in the refrigerator. If your sprouts are still slightly damp, poke a few holes in the plastic bag to let them dry and place them in the refrigerator. Once they do dry, seal them in a new, airtight bag.
Rinse the sprouts with cold water daily to extend their shelf life. Dry them well then put them back in the refrigerator.
