- 6 large egg whites
- 1 1/2 cups sugar
- Preheat oven to 200 degrees. Put egg whites and sugar in the heatproof bowl of an electric mixer. Set bowl over a pan of simmering water; whisk constantly until sugar is dissolved and mixture feels warm to the touch, about 5 minutes.
- Return bowl to mixer, and fit mixer with the whisk attachment. Beat on high speed until very stiff peaks form, about 8 minutes.
- Transfer meringue to a pastry bag fitted with a 1/2-inch plain round tip, such as a Wilton #1A. Pipe bone shapes, each 5 to 6 inches long, onto two baking sheets lined with parchment paper (as shown below). Bake until crisp throughout, about 1 hour. Let cool completely on a wire rack.
Meringues can be baked three days ahead; store in an airtight container at room temperature. Make meringue bones using one continuous motion: Begin by piping a horizontal S shape at top. Continue piping meringue downward in a straight line to form the middle of the bone. Finish by making another horizontal S shape at the bottom. Repeat until all of the meringue is used up.
