Using your iPad as a cookbook is not always the greatest idea; unless you are using Chef Sleeves. Chef Sleeves are plastic sleeves designed specifically for use with the iPad.
Chef Sleeves keep your iPad high and dry no matter how dirty your hands get. The sleeves also preserve the tablet's touch controls, which means that you won't have to worry about being permanently stuck on step two of five. The sleeve is 100 percent recyclable and is actually made out of recyclable materials itself. Perhaps due to all of its other apps and functions, I never realized that an iPad could be a badass cookbook. The Chef Sleeve comes in packs of 25 for $20 and 50 for $34.
