find the dried porcini mushrooms that the recipe suggested, so I substituted fresh shiitake mushrooms.
You can easily
find dried porcini mushrooms and portobello mushrooms at your local grocery store.
Not exact matches
If you opt not to use (or can't
find) the

dried Porcini mushrooms in the recipe which can be
found easily at a well stocked supermarket but if you don't have any and still want to make this risotto that's cool!
