Porcini

Where it grows

Porcini fruit from late summer through autumn under both broadleaf and coniferous trees. They favour mossy, well-drained ground after warm rains, often returning to the same patch year after year.

How to recognise it

The cap is a smooth chestnut to bay brown, sometimes with a paler rim. Underneath are pores rather than gills, white in young specimens and gradually turning olive. The stem is barrel-shaped, cream to pale tan, with a delicate raised network (“reticulum”) near the top. Crucially, the flesh stays white when broken and the mushroom does not bruise blue.

Edibility & cautions

A choice edible — the prized cep of French cooking and the funghi porcini of Italy. Avoid bitter look-alikes such as Tylopilus felleus, which has a pink-tinged pore surface and an intensely bitter taste from even a tiny nibble. Older specimens are often riddled with maggots; cut a porcini in half before bagging it.

Culinary use

Porcini are exceptional dried — concentrating their savoury, nut-and-meat flavour. The dried form rehydrates into risottos, pasta sauces, and broths. Fresh young caps are excellent sliced and pan-fried in butter.
