Chocolate Air Cookies With Chocolate Chips - chocolate

Method

• Preheat oven to 350 degrees F (175 degrees C). Line a baking sheet with baking parchment.
• Melt the chocolate in the top of a double boiler over simmering water, stirring frequently and scraping down the sides with a rubber spatula to avoid scorching. Let chocolate cool slightly while preparing the egg whites.
• Beat egg whites in a glass or metal bowl until foamy. Gradually add sugar, continuing to beat until stiff peaks form. Lift your beater or whisk straight up: the egg whites will form sharp peaks. Stir cream of tartar into the egg whites.
• Scoop some of the egg whites into the cooled melted chocolate and fold until smooth. Fold the chocolate mixture into the remaining egg whites. Stir chocolate chips into the mixture; drop by spoonful onto the prepared baking sheet.
• Bake until cookies set in their centers, 10 to 15 minutes.
