Cook the remainder of the mushrooms. Add minced garlic and thyme and cook for about 2 minutes. Add all purpose flour and dijon mustard and stir to coat evenly.
Add 1 wedge of Nuts For Cheese Black Garlic and melt down until creamy. Add reserved pasta water until you get the desired creaminess/thickness of your sauce.
