I know what you're thinking: Is it really possible to say there's any one small appliance (let alone five!) that every kitchen should have? Kitchens, after all, come in all shapes and sizes. A studio apartment kitchen doesn't have the luxury of space that a suburban kitchen has, so telling me I have to have something in my kitchen (or else!) will probably just bum me out.
So perhaps this is a better way to say it: If you can only fit five small electric appliances in your kitchen, choose these five. Whether you're clearing out a cluttered kitchen or setting up a kitchen from scratch, they're endlessly useful and worth the money and space.
