Whisper

Preheat the oven to 400°F (200°C) for 20 minutes

In a small saucepan, combine the egg whites and cornstarch

Bring the mixture to a low heat, stirring constantly until the cornstarch dissolves and the egg whites become warm but not cooked

Remove from heat

In a blender, mix together the egg white mixture, baking powder, and beat until stiff peaks form

Place the whisper in a piping bag with a large round tip and pipe onto an ungreased baking sheet

Leave about 2 cm of space between each whisper

Bake for 10 minutes at 400°F (200°C)

Reduce oven temperature to 300°F (150°C) and let the whisper dry completely

Use a wooden spoon to prop open the oven door.
