Four Cheese Truffled Macaroni and Cheese

Truffle mac and cheese is one of my favorite things to make when there's a chill in the air. It's great for cheese lovers, like myself, and works well at dinner parties. The leftovers are good too! Truffle oil is one of the best culinary purchases I've made. One little bottle has lasted me a year and can be used with so many things. Top this dish with a pinch of truffle salt if desired.
