Fresh mushrooms have a light to dark brown cap that forms an umbrella over a cream-colored, stout stem. The cap of this mushroom varies in size and ranges between an inch to almost a foot.

Harvesting them when they’re between 4 to 6 inches is best, as larger ones tend to be slimy and damaged by insects or slugs. When sliced, porcini has a half-moon shape.

Flavor profile

Dried porcini mushrooms give dishes rich, earthy, meaty flavor with hints of nuttiness. Fresh porcini mushrooms are tender and meaty in texture once cooked, but dried ones are slightly chewy when rehydrated.

For comparison, porcini offers more robust, wilder flavors than portobello mushrooms. Shiitake mushrooms might be the closest in terms of flavor and texture.
