Dried Mushroom Puree

It isn’t often that you can make a condiment with a single dried ingredient, but since dried mushrooms have become widely available, that occurrence has become more common. If you simmer dried mushrooms until tender, then toss them in a blender with their cooking liquid, you get a thick puree, potent and delicious, something you can use wherever you’d use salsa or even ketchup. You can use any dried mushrooms for this condiment, from the extremely inexpensive shiitakes (also called “black mushrooms”) sold at Asian markets to the prince of dried mushrooms, the porcini. Smoky porcini (usually imported from Chile or Poland) are really good here.
