ALDERSON, WVAuthorities at Alderson Federal Prison have detained Becki Uecker, Martha Stewart's personal assistant, for smuggling a cake-decorating kit to her boss in an almond three-layer cake with lemon-zest icing. 'Ms. Uecker attempted to pass a Dessert Decorator Pro to Ms. Stewart during visiting hours,' corrections officer Frank Wickler said. 'Although this device may be perfect for making stars, leaves, and rosettes, it's considered contraband at a correctional facility.' In addition to the frosting gun, the kit included six nickel-plated tips, two tip couplers, and a storage bag.
