It's a meaty mushroom similar to the portobello, the porcini is often used in Italian cuisine. It's slightly nutty and creamy and has an aroma that has been likened to sourdough. Light brown in color, porcinis can range from one inch to 10 inches across. They're sold fresh, dried and canned. If you're using dried porcinis, soak them in hot water for at least 15 minutes before cooking with them
