Very close indeed. Add the heavy cream and sour cream for the cheese sauce.
I developed my recipe over several years of trial and error, but have it pretty well perfected now. So much so that it's usually requested at gatherings.
I'll post the recipe for anyone interested. This is what I refer to as a single batch, and just reading the recipe will put 2lbs. above the beltline.
1 Lb. Large Macaroni noodles
2 Lbs. Cheese (I like a mix of Cheddar and Pepper Jack)
1 Pint Heavy Whipping Cream
1 Pint Sour Cream
Start boiling water for noodles in a large pot. Add the macaroni once water is at a full boil. You can add salt to the water if desired.
Shred or dice cheese in small cubes. Set aside a handful of shredded cheese to sprinkle on top of macaroni.
Add the heavy cream and cubed cheese into 2 Qt. sauce pan, and use medium heat until cheese is thoroughly melted. Stir often.
Once the macaroni noodles are just slightly under cooked take them off the heat and drain the water. Put the noodles back in the large pot and pour the cheese sauce over the noodles. Add the sour cream and stir well. Be careful not to break up the noodles.
Sprinkle the handful of shredded cheese over the top and bake in a pre heated 400 degree oven uncovered for 45 minutes. Immediately after baking set the oven to broil to brown the cheese on top. Keep a close eye here, and this should only take a minute.
Enjoy!
