🔍 Identify it without mistakes

The "king of mushrooms", the most sought-after of the noble boletes. Hazelnut-brown to light brown cap, smooth and often slimy in wet weather, with a margin that's sometimes paler. Underside made of fine tubes (never gills), white then yellow-greenish with age, turning blue never when touched. Sturdy stem, swollen like a club, white to brownish, decorated with a fine raised white reticulation along its entire length. Pleasant forest-floor smell, mild taste (never bitter).

⚠️ Not to be confused with

Satan's Bolete (Rubroboletus satanas)toxique (severe digestive troubles, sometimes serious)

To tell them apart: Satan's bolete has a greyish-white cap, a bright red stem marked with an orange reticulation, red pores and tubes, and above all, flesh that turns blue instantly and violently when cut — the Porcini never turns blue; Satan's bolete also gives off an unpleasant smell as it ages

Bitter Bolete (Tylopilus felleus)non toxique mais immangeable (extreme bitterness, a single bite ruins a whole dish)

To tell them apart: the bitter bolete has pores that turn pinkish with age (white when young, which makes it deceptive) and a dark, almost black reticulation very marked on the stem; tasting a small piece of raw flesh is enough to decide (immediate and persistent bitterness), to spit out of course

🍽️ Eating it

Partscap, stem, tubes in young specimens
Seasonjuin-novembre, peak in september-october
Tastenutty, forest floor, one of the most flavorful boletes

Preparation : always cooked; remove tubes that have become greenish and spongy in older specimens (they are hard to digest); pan-fried, dried (rehydrates very well and concentrates the aroma), or cooked with garlic and parsley
