Porcini-crusted cod with thyme-butter sauce

This porcini-crusted cod with a delicious pan butter sauce comes together in less than 20 minutes and is the perfect weeknight dinner. We love porcini mushrooms, as they add an earthy note to the finished dish, but you can also use any dried mushroom that you have on hand as a substitute. Or you can omit them altogether if you don't own a spice grinder or have another means to grind up the mushrooms, and the fish will still be delicious, as the pan sauce of white wine, chicken broth, thyme, and of course butter holds its own and is more than enough to complement the cod.
