SO hang in there, they're coming soon.
Before I go, just wanted to update any interested folk on the progress of my macaroni search- right now I have before me 12 cookbooks that all contain recipes for macaroni and cheese. I am planning to read them all and do a bit of comparison to find out what it is that people think should be in good mac 'n cheese. Once I'm satisfied that I have a good understanding, I will then choose a few recipes to try over the next few weeks. (Since I'm pregnant, I have a pretty low tolerance for repeated meals, otherwise I would just make all of them in a row.) If you wish for your favorite recipe to be in the running, act now or forever hold your peace.
In the mean time, you might check this out.
