How come nobody ever told me you can make a perfectly good white sauce in the microwave in two minutes??? I discovered the general proof of concept trying to make some fast macaroni and cheese from refrigerated noodles. Then just now I wanted some for me. Grated cheese in a bowl, sprinkle in a generous coating of flour (I use whole wheat), mostly cover with whole milk, and microwave until it gets hot, stir to blend the cheese, microwave until it puffs up, then stir. Done. Took one minute then one minute in our microwave with a half a bowl full. Easy peasy, no gradually adding the milk to the roux, no standing over the stove. So it isn't gourmet.
