In a small bowl, beat egg white, salt and cream of tartar on high speed until stiff peaks form.
In a large bowl, mix milk and extract until blended. Stir in coconut and baking powder. Fold in beaten egg white.
Drop coconut mixture by rounded tablespoonfuls 2 inches apart onto greased baking sheets. Bake 11-13 minutes or just until golden brown. Remove from pans to wire racks to cool.
