Separate egg yolks and whites in seconds with this inventive double-cup strainer. Whites drain into one cup while yolks are dropped into the other, and the cups double as storage for any unused portions. Whites drain into white cup; simply flip the strainer over to drop yolks into the yellow cup. Leftover portions can be refrigerated in the cups for use in other recipes, minimizing waste. Easy snap-together use. Includes two lids for storage. A Williams-Sonoma exclusive.
