Soak porcini mushrooms with hot water for 10-15mins. Dispose water. Rinse shrooms with warm water for 3-4 times until there's no soil residue. Chop the garlic. Heat pan with olive oil & pan fry garlic
Meanwhile, chop the fresh thyme. You can do this much earlier during the prepping stage.
Add the tendered porcini mushrooms and pan fry for 3mins in medium heat. Add the white wine and bring to boil. Allow to evaporate but not entirely dry.
Add milk and fresh thyme into the pan. Bring to boil. Add 1/2 the cream and the remaining 5mins before you serve the dish. Taste with salt and pepper. Note: add a pinch of sugar to balance the taste
Place the spaghetti onto a plate and put the porcini on top of the pasta. Garnish with a small wedge of lemon. Serve hot. Note: lemon juice will help to decrease the filling-ness of this dish.
