But I'm not quite as puzzled as this person who asked: "For dinner, the recipe calls for a 13x9 baking dish. I only have a 9x13 (oblong) cake pan. Can I use my cake pan?"
Fortunately, there are people who stopped scratching their heads at the stupidity of the question long enough to answer: "Yeah, rotate the 9x13 pan 90° and it turns into a 13x9 dish."
Watch closely, and I'll show you how it's done.
Whoa-- the magic of cooking.
