Our apartment in Paris didn't have any ice trays but Kelly found these at the supermarket. Cub Facil are disposable plastic bags that are divided into cube-size compartments. You just fill a bag with water, tie it closed, freeze, and then tear out the cubes as you need them. Each box is about US$2 and contains ten bags. (Click on the photo for a better view.)
Update: Thanks to the dozens of readers who responded that these ice cube bags are old hat in most countries outside the United States. News to me!
