Cooking Tips
Soak dried ones in lukewarm water for 15 to 20 minutes. They will rehydrate to 2 to 5 times the size they were when dried, and look a bit like a big, shiny black ear. When rehydrated, cut off any woody material attached to the base, as well as any tough skin or bark, and rub lightly with your fingers to clear off any gunge. Chop and slice as needed.
For a stir fry, rehydrate and cut into strips.
If cooked too long, they will lose their firmness, which would be a drag because their texture is just about the only reason to use them in the first place. Consequently, add them to dishes at the end of cooking.
Dried ones can be also be powdered and used as a thickener for soups or a spice base.
Substitutes
Ultimately, it doesn’t really matter if you use Wood Ear Mushrooms or Cloud Ear Mushrooms; they are pretty interchangeable.
Storage Hints

Language Notes
