- 4 O Organics Large Egg whites, at room temperature
- 1/4 teaspoon salt
- 3/4 cup O Organics sugar
- 4 ounces bittersweet chocolate, chopped
- 3/4 cup shelled unsalted roasted pistachios, chopped
- 1 teaspoon grated orange peel
- Line two 10-by-15-inch baking sheets with cooking parchment or silicone baking liners. Separate egg whites into a bowl (save yolks for another use or discard). With an electric mixer at medium-high speed, beat whites and salt just until stiff (but not dry) peaks form, 2 to 4 minutes. Reduce speed to medium and add sugar gradually, beating until it has dissolved and whites are glossy and like marshmallow creme in texture, about 3 minutes.
- With a flexible spatula, gently fold in chocolate, pistachios, and orange peel.
- Drop mixture in tablespoon portions about 1 inch apart on baking sheets. If desired, swirl the back of a spoon (or your finger) around cookies to shape.
- Bake in a 250 degrees F regular or 225 degrees F convection oven until meringues appear set and are just beginning to turn pale gold at edges, about 50 minutes, switching baking sheet positions halfway through baking. Turn off oven and leave cookies inside on sheets until dry in the center (break one to test), at least 4 hours or up to 12. Store airtight at room temperature up to 2 weeks.
