I don't think I'd eat reconstituted dried mushrooms without cooking them. And don't forget to dry them off after they're rehydrated before you use them in your recipe, or you may end up with more liquid than you really wanted.

You'll want to reconstitute them in just boiled water first. After a few minutes, this will plump them and make them tender enough to chop up (and eat!). And then as a bonus, the water will turn into a delicious mushroom stock.

Here are a couple great recipes to use them:
