When I bring my fresh morel mushrooms home I always place them in cold water with salt added to encourage any forest critters to exit before I cook them. I always do this twice with clean salt water.
The Ratio is 1 tsp. salt per 2 cups cold water.
Morels can be dried with a dehydrator or in the sun as they would in Italy. Dried morels are great in soups and sauces.
In 2018 the going price for fresh morels in Door County Wisconsin is $35 per pound and they are worth every penny!
Eat, drink and enjoy!
