Begin by slicing the mushrooms, around a 1/4 inch thick
Melt a table spoon of butter with a tablespoon of olive oil over medium high heat until it begins to foam and bubble
Add the mushrooms and cook until golden, tossing regularly. This should take around 7-8 minutes.
Once the mushrooms have started to cook, add your pasta to a large pot of well salted boiling water and stir
Once the mushrooms are coloured, add the minced garlic and thyme leaves and saute for a minute to soften
Add the splash of bourbon. You can either flambe (ignite and cook till flames subside) or just let it bubble away for a minute
Add the stock and then the cream and begin to reduce until thickened slightly and the sauce coats the back of a spoon
grate in the parmesan cheese and stir - taste for seasoning
When the pasta is 1 minute from being ready, remove and add to the sauce in the frying pan and toss to coat the pasta
Using tongs, place into a pasta bowl or plate, garnish with some chopped parsley and a little grating of parmesan and black pepper, with a drizzle of truffle oil
