Soak the dried porcini mushrooms in cold water for a couple of hours, then gently squeeze out the excess water and chop them finely.
Finely chop the onion. Cut the fresh porcini mushrooms into small pieces. Mince the garlic into very small cubes.
In a skillet, melt 20 g of butter over low heat and sauté the garlic until soft.
Add the chopped fresh porcini mushrooms and sauté for 1-2 minutes, stirring frequently. Season with salt and pepper, then remove from heat.
In a separate pot, heat the chicken broth over low heat until it’s almost boiling. Lightly season with salt.
In a wide, heavy-bottomed pot, sauté the onion in 30 g of butter until translucent. Add the finely chopped soaked dried porcini mushrooms and sauté lightly.
Add the rinsed rice, stirring until it is coated with the butter.
Pour in the white wine and let it absorb completely. Then add 1-2 ladles of the broth.
As the broth evaporates, continue to add another ladle at a time. Cook for about 20 minutes, or until the rice is tender.
Once the rice is ready, stir in the sautéed fresh porcini mushrooms and parsley, and let it sit off the heat for 1 minute.
Finally, mix in the grated cheese and 40 g of very cold butter. Add spices to taste if desired.
