Watch to see Mario and Gwyneth's full list of favorite things in the kitchen.
Gwyneth says she loves to have a glass of wine while she cooks and has found a gizmo that keeps her half-full bottles fresh. "In my house, there's always wine left over," she says. Just place the wine saver on top of the bottle, pump, and the air is sucked out of the bottle. "And then the next day you can have the other half of your bottle of wine," she says.
See how Gwyneth can eat what she wants and stay in shape!
