CoCo asked, "How do you dress up mac and cheese? [all right, somebody gave me these here boxes of gluey elbows]"
Outlaw gave you a good starting point. I would add that if your elbows are gluey, its probably because they're overcooked. try boiling them for a minute less than the package directions suggest, keeping in mind that they will continue cooking as you add the cheese sauce and put the mixture into the oven to bake.
Better yet, try making a "grown-up" version of mac n' cheese with Gruyere and a nice stinky Italian Fontina instead of cheez-whiz. ZoundS, that is GOOOOOD!
As for the contamination of canola oil with fungus... fungal spores are EVERYWHERE; but they're killed by application of heat: that's part of the benefit of COOKING food. I'm not one of the proponents of raw food. I believe the art of cooking contributed greatly to the rise of homo sapiens. Most other species can't even prepare a proper béchamel sauce!
If I'm going to use vegetable oil for cooking, I prefer peanut oil, and most good oriental chefs would agree with me. Obviously I'm not allegic to peanuts. Lard is KING, however. I hear your muttered sub-vocal objections - did you want to live forever?
Is life without pork fat even really life?
Think on these things, ponder on them.
