Mac & Cheese? Yep, it's even the stuff from a box. Western Family brand. Well, one day I decided to make it for lunch, and halfway through making it, forgot that we had finished our last gallon of milk for breakfast. Well, I didn't want to run to the store, so I looked in the fridge and tried to think of something liquid I could add that wasn't water. Then I spotted the sour cream! It is made from milk! I decided to give that a try. It turned out delicious, actually! It was creamy ( slightly sticky), and the cheese stuck to the noodles so good! It had the texture almost like alfredo sauce.
