A strainer for use with combining beverages and cold food includes a bottom section sized for insertion into a beverage container, and a side section projecting substantially vertically from the bottom section and sized for insertion into a portion of the beverage container. At least one of the bottom and side sections is liquid permeable, and the bottom section and side section are separately or collectively capable of retaining ice pieces when the strainer is in the container. A method for retaining ice in a container capable of holding a liquid includes placing a strainer capable of retaining ice in a container capable of holding a liquid, adding ice to the container such that at least some of the ice is retained by the strainer, placing a liquid in the container, and removing the strainer from the container.
