{"type":"firestarter.listing","listing":{"id":"lst_-bWQMZa6","product_name":"Porcini Powder","category":null,"description":"Earthy porcini adds rich umami flavor to meats and stews.\n Perfect in rubs for pork, chicken, or even meatloaf, porcini mushrooms bring a deep, savory taste. One of our best customers, Rich, swears by it in his signature chicken stew blend. It's the lead ingredient in our Porcini Spiced Salt. And if you love umami, we now carry MSG. Looking for a more subtle mushroom flavor? Try shiitake powder. \n Details: All-natural. Origin China. \n Shiitake vs. Porcini for Culinary Use:\n \n \n Shiitake: Has a milder, earthy flavor with subtle woodsy undertones. They add a delicate umami depth, making them ideal for Asian-inspired dishes like stir-fries, ramen, and dumpling fillings. Shiitake works well in recipes where a balanced, less overpowering mushroom flavor is desired, especially in vegetarian and lighter dishes.\n \n \n Porcini: Offers a bolder, more robust flavor profile with intense umami and nutty, almost smoky notes. Their rich taste makes them perfect for heartier dishes like risottos, stews, and meat rubs. Porcini adds a powerful earthy richness, enhancing sauces, gravies, and roasted meats with deeper flavors than shiitake.\n \n \n Zero-Waste Spice Refills Packaged in Compostable Packaging:\n \n \n Small Refill: scant 1/4 cup volume (0.3 oz net weight)\n \n Large Refill: 1/2 cup volume (0.8 oz net weight)\n \n Refill packaging is made from plants and safe for home composting.
