How are Porcini doing in Valais this October?

Porcini usually come up in Valais from August to November, and right now they’re at 50% and looking good.

Fruits after warm, humid spells when soil temperatures sit in the mid teens Celsius and a good soaking rain follows a warm period. A typical trigger is heavy rain after several warm days, with flushes appearing roughly one to two weeks later.

Unlike many boletes, the pore surface of Boletus edulis does not bruise blue when cut or handled, which helps separate it from look-alikes.

Grows in mycorrhizal partnership with trees, especially under pine, spruce, birch, beech and oak, on well drained soil. Found in conifer and broadleaf woodland and along woodland edges and tracks.

Keep fresh caps in a paper bag in the fridge and use within a couple of days, as they spoil and get wormy fast. Slicing and drying is the classic long term method; they also freeze well if briefly sauteed first.

Slice young firm caps thin and fry in butter with garlic and parsley, or add to risotto and pasta sauces. Older or wormy specimens are best dried and ground into a powder to deepen stocks, soups and gravies.

Can be confused with the bitter bolete (Tylopilus felleus), which has a darker net on the stem, pinkish pores when mature and a strongly bitter taste, and with red pored boletes. Avoid any bolete with red or orange pores or flesh that stains strongly blue.
