Came up with an interesting use for some cubed butternut. I also had some diced pancetta. I fried up the butternut in the pancetta grease adn set aside then preceded to make a pretty standard carbonara and folded in the butternut. It was a nice change. and a nice way to use up some butternut since i'm neck deep in it after farmshare's bumper crop.
My initial thought that I ran by Jacob was to make a mash and thin it out and create the sauce that way, but in order to not weigh down the pasta, I went with the cubes. Great idea. Try it!
