How to prepare Tagliatelle ai funghi porcini (porcini mushroom) - True Recipe from my mother

Yesterday I went to the food market in Gaillard and I found great fresh porcini mushrooms at a decent price , so I decided to cook one of my favorite dishes, an heritage from my mother :

Tagliatelle ai Funghi Porcini , Tagliatelle with Porcini Mushroom  
Ingredient  for 4 people: 

• 250 gr of Tagliatelle all'Uovo  - I bought them at Leclerc Annemasse and I foudn the Brand De Cecco , however this type of pasta can be found also at Coop Geneva and  Manor 
• 300 -400 gr porcini mushrooms
• 4 tablespoons of  extra virgin olive oil
• 1 clove of garlic peeled 
• A small bunch  of parsley -chopped
• Salt
• Pepper
• 2-3 tablespoons of Parmesan cheese

Process (preparation: 15 min. cooking: 20 min.)

First you have to prepare the porcini mushrooms , cleaning the mushrooms is an operation that requires ability and a bit 'of time, don't use water , remove or even cut the lower parts of the stem if there is a lot of earth then use a kitchen brush to clean the chapels ,finally clean all mushroom with humid but not wet kitchen paper .

Now cut the mushrooms in pieces (not in slices ! )  checking  that the  inside part is perfectly intact and white. 

Cut the parsley in very small pieces, I always do using my grandmother 's "half moon knife" but you can use any type of mixer 

Put the oil in a large pan , once the oil has reached teh highest temperature , add the peeled garlic clove and the mashed parsley , then cook 1-2 minutes max and then add the porcini mushrooms, reduce heat to medium heat  temperature and turn frequently for 20 minutes. Add a little salt and pepper and keep softly turning .You might add a bit of hot water if  the mushrooms are too dry to avoid they burn.

 Boil pasta in salted water; and when it is almost cooked , 1 minute before the final cooking time, remove the garlic from the pan ,drain the pasta and pour it inside the pan where you have cooked the mushrooms , stir the mushrooms sauce with the tagliatelle for 1 minute adding if you need a couple of spoons of the water where you cooked the pasta 

Serve the tagliatelle with porcini ushrooms immediately with a little chopped parsley on it, olive oil and parmesan cheese.
