One could add margarine and/or milk to the Mac & Cheese if it becomes too thick.The only mac n cheese I can eat is the Kraft box with the cheese powder, anything else is too thick and makes me vomit.
One can also sprinkle Parmesan or other cheese (grated, e.g., Provalone, Gouda, Havarti, Manchego, Sirene, . . . .) according to preference on top.
DittoSpoon, I need to shovel it into my mouth quickly
