The Porcini mushrooms, as it is known in Italy, is more commonly known as cèpes in the French culinary world, and the Penny Bun in America (it is never called Penny Buns in the UK). It’s scientific name is the Boletus edulis, and it is part of the Basidiomycete group of fungus, the fungi group with contains the majority of edible mushrooms. As the name implies, ‘edilus’ in latin simply means that it is edible. In italian, the word Porcini can roughly be translated to “baby piglets”. Like all members of the Basidiomycete group, the fungus lives underground by growing mycelium. Mycelium are long white strains that grow outwards in search of nutrient in the soil. Along the way, the hyphae (branches of Mycelium) secrete enzymes to digest the nutrients in the soil, before absorbing it back in. The actually Porcini mushroom that sticks out of the ground, is actually the fruiting body of the fungus, with its sole purpose being to spread its spores. Armed with this information, when harvesting Porcini mushrooms, hold the stem of the mushroom as close to ground level as possible before twisting gently to break the hyphae. Do not pull the mushroom as this will damage the underground mycelium, while cutting the mushroom with a knife will cause the remaining part of the mushroom to rot, thus also harming the mycelium.

Another important fact to keep in mind is that Porcini mushrooms form symbiotic relationships with trees. This means that they share nutrients with some species of trees in exchange for other nutrients which they might be unable to find themselves. Because of this, Porcini mushrooms are usually found at the base of certain species of trees such as chestnut and pine trees. When harvesting porcini mushrooms and choosing porcini mushrooms at a market, be sure to check the underside of the mushroom. Similar to button mushrooms, you do not want to choose those that have an opened cup, where their gills are already visible. You would prefer to choose those which are still closed, where their gills are not visible on the underside of the mushroom. If the underside of the mushroom has becoming a spongy yellowish brown, the mushrooms are already overripe and should not be picked/chosen.

If they instead have a pinkish reticulum, they are most probably the closely related Bitter Bolete, which while harmless, are extremely bitter and will ruin an entire dish. Along with this, remember that any Porcini mushrooms that have a red underside or a blue-ish thinge should not be taken as they are most likely poisonous.

Like all other mushrooms, it is preferable to clean them with a mushroom brush or a damn cloth. Never soak or wash them in water as they are water permeable and will soak up water very quickly, diluting the flavour and causing your mushrooms to go soggy. If the mushrooms are extremely dirty, it is still acceptable to quickly rinse the mushroom in cold water. To prepare fresh Porcini mushrooms, I usually scrape any grit and dirt from the mushroom before slicing them length wise. If the mushroom are fairly large and old, I sometimes also peel them to remove their tough outer coating.

Tajarin is a type of egg pasta that is traditional in the Piedmont region of Italy. It is similar to tagliatelle but thinner (~3mm). Both tagliatelle and tajarin are made from the same recipe which contains semolina flour, salt and eggs. However, they not only differ in place of origin, they also differ in uses. Tajarin, with its thinner width, is better suited for light sauces and delicate flavours such has white sauces and mushroom sauces. Conversely, tagliatelle with its high surface area, is more suited to heavy meat sauces such as a ragu. This being said, tajarin can also be found to be served with meat sauces in Piedmont. 

This dish consists of sautéed Porcini mushrooms in garlic and butter, served with fresh Tajarin and a sauce of Nepitella and reduced Porcini stock.

Tajarin with Fresh Porcini Mushrooms and Wild Calamint

  • Fresh Porcini Mushrooms (sliced length wise)
  • Olive Oil
  • Garlic
  • Salt
  • Nepitella (Wild Calamint)
  • Mushroom stock
    • Dried Porcini Mushrooms
    • Vegetable Stock
  • Fresh tajarin
  1. First, fry the garlic in olive oil until golden brown before adding in the fresh Porcini mushroom and sweat until soft but still with a meaty texture. Add salt to taste before setting aside.
  2. To make the mushroom stock, reconstitute the dried Porcini mushrooms in hot vegetable stock for around 15 minutes.
  3. Next, in the same pan used to fry the Porcini mushrooms, add in mushroom stock to deglaze the pan, before adding on fresh Nepitella.
  4. Reduce the stock until thickened to desired consistency. To cook the fresh tajarin, prepare a shallow pan with boiling water, olive oil and salt.
  5. Once boiling, add in the tajarin and cook until soft but still al dente.
  6. Drain the tajarin and mix the tajarin into the sauce, before adding the porcini mushrooms back in the pan and mix everything together.
  7. Finish with more Nepitella. Fresh tajarin (or pasta in general) does not take long to cook, only a minute  or so.
  8. If using dried tajarin, the cooking time will be considerably longer. To help thicken the sauce, pasta water can be added to the sauce when reducing, as the starch in the pasta water will help thicken the sauce.
  9. As usual, salt is added to pasta water to help season the pasta. Mushroom stock can also be added to the pasta water to give the pasta notes of mushrooms.

This dish is not a traditional Italian dish as it consist of a mix of Piedmont and Tuscan influrence. The use of Nepitella is widespread in the Tuscan region and is the classic accompaniment for Porcini mushrooms. In contrast to this, the use of Tajarin comes from the Piedmont region, and is rarely found in Tuscany. To me the thin texture of tajarin works better with this sauce, thus explaining my choice in blending the two styles.

Nepitella, also known as wild calamint, is an aromatic herb which is common is Tuscany. It is rarely used in most of the english speaking world, but is a common ingredient in autumn and winter dishes, especially in Florence. In my opinion, Nepitella characterises Italian cooking extremely well, as it’s taste is not only fresh and sharp, but has the flavour combination of oregano, mint and basil, three of the most common herbs found in italian cooking. This of course is just a description, and the flavour of nepitella itself is unique and somewhat on the floral side. A little nepitella goes a long way and should be adding to dishes with care.
