MOM Tip: An Easy Way to Store Asparagus for Up to 2 Weeks.
With a sharp knife, cut off about an inch of the tough bottom ends.
Place the asparagus in a quart size jar and fill it with 1 to 2 inches of water.
Place a plastic bag (such as a produce bag) loosely over the jar so it is not touching the asparagus. Pull and twist the bottom of the bag, tucking it under itself to keep it sealed.
Place in the refrigerator till needed. Wash when ready to use.
