In a small bowl, whisk together flour and salt. Add flour and salt to the mixture and stir to combine. Shape dough into 1-inch balls and dip into slightly whipped egg white. Roll each ball into crushed walnuts and place on a parchment-lined baking sheet.
Press thumb into the center of each ball and make an impression deep enough for adding jam. Add 1 teaspoon fruit spread to cookie centers. Bake cookies until golden, 8-10 minutes. Remove cookies and allow to cool before eating.
