Prepare a pot for cooking tagliatelle and fill it with salted water. When adding tagliatelle the water should be boiling.
If you're preparing tagliatelle with fresh mushrooms, clean them with a dry cloth and cut them to thin, longer slices.
Peel and crush the garlic cloves. Dice the onions to small pieces and fry them in hot olive oil (slowly) until they become dark yellow and tranluscent.
Add the mushrooms to the pan and saute for a few minutes. When the liquid evaporates, pour in the cream with a half glass of water or wine. Add salt and pepper to the mushrooms and cook on low heat for another 5-7 minutes.
In the meantime, cook the tagliatelle boiling, salted water for five minutes.
When cooked and strained, add them to the mushrooms and serve the delightful dish fresh and hot, sprinkled with parsley or parmesan cheese. Enjoy :)
NOTES
If possible, use cold-pressed organic olive oil for cooking porcini.Fresh, homemade tagliatelle will taste indescribably better than premade dry pasta from the shop.Use fresh, healthy porcini mushrooms preferably picked on the same day. Do not keep your mushrooms in the refrigerator for longer than a day.Adding half a glass of white wine will delightfully enhance the rich taste of the porcini mushrooms with the cream. Don't wash porcinis under running water; use a dry cloth to clean them instead.Cook only the amount of mushrooms you plan to eat to avoid reheating. You can reheat tagliatelle after being stored properly in a closed container in a refrigerator. The best way to reheat them is in a pan with butter and serve them with freshly made porcini.
