Joie's Yolky Egg Separator is a fun way to separate egg yolks from egg whites with less messy clean-up. It's so easy to use. Simply clip yolky onto the edge of a bowl or cup and crack the egg into the center. Yolky catches the yolk and allows the egg whites to flow through into the catch bowl. A helpful addition to baking tools for separating eggs for baking cakes, making egg custards, meringue pies, homemade mayonnaise and more. Whimsical, yet useful gadgets and gizmos make baking and cooking easier and fun and bring more joy to the task. Made from BPA-free plastic. Hand wash in warm, soapy water.
