I have been experimenting with mac and cheese for as long as I can remember. I have tried all of the cheese sauces it seems like ..... milk and cheese, roux based, Velveeta based, combinations thereof....... as of late I have been liking the Kenji J. alt Lopez recipe. No roux ( contrary to belief, it is highly over rated), quick and easy and its easy to do as a double boiler method to cook the noodles and the sauce at the same time !! I have experimented with recipes from Vincenzo plate, Joshua weisman, Matty matheson, martha Stewart......... Kenji is where I have landed... for now. In cane anyone was wondering, the Kenji recipe utilizes American cheese because it contain sodium citrate ( I used Velveeta) , after two hrs on the stove it wasn't a congealed block, it was still thick and creamy , held its consistency and the noodles didn't absorb it. Exactly how I like it, and easier than messing with measuring out sodium citrate and getting the ration right, which was my previous method........ so what's your go to Cheese Sauce recipe???
