I don't know why they call it Mac & Cheese Starter -- it does just fine by isself. Seriously, it's got a fancyass cheeseeatingsurrendermonkey name, but you could be done making your first batch of bechamel twenty minutes from now. Melt a stick of butter in a pan add 8 tb of flour, stir until light brown, add 3 cups or so of milk, and stir to combine. It will look all weird for a minute, when you add milk, but it will smooth out. add a bunch of grated cheese, combine w/ cooked pasta, and you have got badass mac & cheese. Not. Complicated.
