Instruction
Limited raw use of young, firm porcini is documented, but the Swiss Federal Food Safety and Veterinary Office advises against eating wild mushrooms raw. Have the harvest checked by an expert and prefer a cooked preparation.

Guide contents

Season

The indicative period runs from June to October, often beginning early in warm broadleaf woodland.

Habitat

Open broadleaf woodland, edges and warm sites, chiefly beneath oaks and beeches, but also hornbeams and sweet chestnuts.

Method

Check several visible features before retaining a species name.

Three features to check on the specimen.

  1. Dry, light brown cap

    The hazel to light brown cap is dry and finely velvety when young; it may crack naturally without becoming scaly.

  2. White, then olive pores

    The very fine pores are white to cream when young, later yellow and olive, never pink or red.

  3. Extensive pale network

    The stout, cream-white to pale beige stem bears a clearly visible white to cream network that often extends well down its length.

Examine the specimen in this order.

  • Check the dry pale cap, age-appropriate pore colour and extensive pale network together.
  • A longitudinal section should show white flesh without marked blue staining and a continuous tube layer.
  • Reject any specimen with pink, red or orange pores, a dominant dark brown network or marked blue staining.

Features incompatible with this species.

  • Boletus edulis is very similar; Summer bolete is generally drier and more extensively netted, but an image alone may not suffice.
  • Boletus aereus has a much darker bronze cap with pale, then yellow pores.
  • Tylopilus felleus develops pink pores and a dominant dark brown network.
  • Rubroboletus satanas has red pores, a yellow-and-carmine stem with a red network and may turn blue.

From an inspected basket to the kitchen

Drying, storage and two recipes for Summer bolete.

Two fully cooked preparations for a collection of Summer boletes that has been identified with certainty and inspected by an expert.

Ingredients

  • 500 gFirm, identified and inspected Summer boletes
  • 2Finely sliced shallots
  • 2 tbspOlive oil
  • 20 gButter
  • 2 tbspChopped flat-leaf parsley
  • 1 pinchSalt and pepper

Method

  1. Inspect and prepareKeep the collection separate until inspection. Confirm the cream to olive-yellow pores and the extensive pale network on the stem. Clean the accepted specimens and cut them into even slices.
  2. Evaporate the waterHeat the oil in a large pan and cook the slices for 15 minutes, stirring until their water has evaporated.
  3. Finish cookingAdd the shallots and butter, then continue cooking for 10 minutes, stirring regularly.
  4. ServeAdd the parsley off the heat, season and serve immediately with polenta or toasted bread.

Use only an inspected collection of Summer bolete. Reject specimens with pink or red pores, a predominantly dark brown network or marked blue staining. The recipe times do not validate identification or safety.

Ingredients

  • 400 gFirm, identified and inspected Summer boletes
  • 250 gPolenta
  • 1 lHot vegetable stock
  • 2 tbspOlive oil
  • 30 gButter
  • 40 gGrated hard cheese
  • 1 pinchSalt and pepper

Method

  1. Prepare the collectionUse only specimens accepted after inspection. Confirm the cream to olive-yellow pores and the extensive pale network on the stem. Remove damaged parts and slice the mushrooms.
  2. Cook the mushroomsCook them in the oil for 20 minutes, stirring regularly until their water has evaporated.
  3. Cook the polentaPour the polenta into simmering stock and stir for 10 minutes, or follow the product directions, then add the butter and cheese.

Documented limit

Drying Summer bolete: no retained protocol

This guide validates no species-specific drying time.

This guide does not apply a generic drying time to Summer bolete. It recommends short refrigeration before cooking so that the method remains documented and appropriate for the species.

  1. Keep the batch whole, identifiable and separate until the inspection required by the guide.
  2. Do not automatically apply the temperature or duration intended for another species.
  3. Use the “Short refrigeration before cooking” method detailed in the Storage section instead.
  4. Read the general drying guide to understand equipment, checks and safety limits without inferring a protocol for this batch.

Storage

Recommended storage

Short refrigeration before cooking

Cook promptly after inspection of the collection.

No drying procedure specific to Summer bolete is recommended here. Keep the inspected collection separate, cool and identifiable until it is fully cooked.

  1. Keep only firm, inspected specimens after removing damaged parts.
  2. Keep the unwashed collection in a clean, breathable container, separate from every other species.
  3. Refrigerate promptly and keep the identification label with the collection.
  4. Cook promptly and discard any specimen that becomes soft, slimy, waterlogged or has an unusual smell.
