I wouldn't even bother posting this, except that it involves cheese. All which involves cheese is worth speaking of.
It came to me in a dream: I was making some broccoli cheese soup, and added too much milk by mistake. Milk is of course a good thing, but too much of it screws up the viscosity of the soup; I like it good 'n thick. So, unconscious problem solving prompted my imagined self to add some flour. That thickens stuff up, right? Not bad for dream-logic.
So the next time I made broccoli cheese soup in waking life, sure enough I added more milk than I'd intended. Applying the well-worn scientific principle, "oh-what-the-hell", I mixed in one of those little fancy measuring spoon's worth of flour.
Worked like a dream.
