Porcini is really a small group of closely related boletes. The summer cep (Boletus reticulatus, also called Boletus aestivalis) fruits in warm broadleaf woodland from late spring into summer, well before the main autumn flush of Boletus edulis, so an early-season find is entirely natural. The forecast reflects this wider group.
Forms mycorrhizal partnerships with conifers (spruce, pine) and broadleaves (oak, beech, birch), so look at the edges and clearings of these woods. It favours mossy banks, well drained acidic soils and the grassy verges of woodland paths rather than dense leaf litter.
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, and taste a tiny piece of any doubtful bolete to detect bitterness.
Stockholm sits where Lake Mälaren spills into the Baltic, a low, glacier-worn landscape of rocky islands, inlets and shallow bays that fan out into the vast archipelago. Inland the terrain is gently rolling, with smooth granite outcrops, scattered lakes and bands of forest threaded between fields and suburbs. The woods are typically Nordic: Scots pine on the dry rocky ridges, Norway spruce in the damper, mossier hollows, and birch, oak and aspen mixed in. Spruce stands and mossy ground are the place to look for chanterelles and porcini, while the oaks and birches host a wide range of boletes and other edibles.
The climate is humid and fairly cool, tempered by the surrounding sea, with no real summer drought and steady rainfall from late summer into autumn. Warm, wet August and September weather after the first cooler nights is what reliably triggers the main flush. Foraging is woven into local life here, with public forest freely open under allemansrätten (the right of public access). Chanterelles, porcini and funnel chanterelles are the classic prizes, and you rarely have to drive far from the city to reach productive woodland or take a boat out to the islands.
