3-4largeegg whites, room temperature(105 to 130 grams)
Instructions
Preheat oven to 350 degrees. Spread the pecan halves on a baking sheet and toast for about 7 minutes or until pecans are aromatic. Alternatively, you can toast them in a large skillet. Let the pecans cool.
Reduce oven heat to 325 degrees F. Line two baking sheets with parchment paper.
In a large bowl, sift together powdered sugar, cocoa and salt. Stir in chopped chocolate and chopped pecans. Add three of the egg whites and stir with a heavy duty scraper or large mixing spoon until mixture is shiny. If it is very thick, crack the fourth egg and drizzle in a little white, stirring until mixture is a little looser, but still holds its shape when dropped.
Using a generously heaping tablespoon measure, drop mounds of batter about 3 inches apart onto baking sheets. Bake until cookie tops are dry and crackled, about 20 minutes, rotating baking sheets halfway through. Allow the cookies to cool on the baking sheets for about 5 to 8 minutes, then carefully peel away from parchment and let cool completely.
