Perfect meringues depend on totally yolk-free whites. The seemingly fussy step of separating each egg into a small bowl before combining them guarantees yolk-free whites for bakeshop-quality meringues every time. These crispy little morsels travel well and make great gifts too.
Make Ahead Tip: Cookies can be held at room temperature in an airtight container for up to 5 days or in the freezer for up to 1 month. If stored meringues are chewy, bake at 200°F for about 10 minutes to restore their original crisp texture.
Tip: To get the most volume from beaten egg whites, it's best to start with whites at room temperature. Submerge them in their shells in a bowl of lukewarm (not hot) water for about 5 minutes before using.
