The iPad makes a nice digital cookbook, huh? But using it around messy ingredients can get downright ugly and trying to use the touchscreen when your hands are covered in whatever it is that people who know how to cook have their hands covered in is a bad, bad idea.If only there existed a disposable protective iPad cover made especially for cooking. Wouldn't that be something? They could call it the Chef Sleeve. I put the Chef Sleeve to the test in the above video wherein I attempt to make something called "toast" for the first time. What could possibly go wrong?
