Morel mushrooms are often considered a delicacy in the United States. Their window for growth is short, typically no longer than a month, and the conditions must be just right in order for the mushrooms to grow. For this reason, morel mushrooms can be difficult to find and expensive to buy. If you happen to get your hands on morels, make sure you properly store them as they can turn rotten in as little as 12 hours in improper conditions.
Fill a large mixing bowl with lukewarm water. Leave at least an inch of space at the top as the water level will rise when the mushrooms are added.
Dump the mushrooms into the water and let them soak for 30 minutes. If all of the mushrooms do not fit in the bowl, you will have to do multiple soaking sessions. The soaking process is necessary to kill bugs in the holes and crevices of the mushrooms.
Pour the contents of the bowl through a colander over a sink or tub to separate the mushrooms from the water.
Cut the mushrooms in half length-wise with a sharp knife. This will help conserve space and also cut down on your preparation time when you decide to cook the mushrooms.
Put the cut mushrooms into a large dry bowl. Cover the bowl with moistened paper towel and store them in the refrigerator for up to a week. When the paper towel dries out, replace it with more moistened paper towel.
Use the mushrooms within a week.
