You can easily use whatever mushrooms you can get. White mushrooms, brown mushrooms, portobello, chanterelle, and porcini are all great options. If you want to add some extra mushroom flavor, you can add about 0.5 ounces or 15 grams of dry porcini mushrooms. You just have to soak them in half a cup of water for 10 minutes first, then add them with their soaking water to the pan with the other mushrooms.
