Preheat oven to 375 degrees F (190 degrees C).

Sift together flour, salt, cinnamon, nutmeg, and clove in a bowl.

Set aside the dry ingredients.

In a separate small bowl, combine applesauce and baking soda.

Set aside the applesauce mixture.

In a mixing bowl, cream together vegetable shortening and sugar until light and fluffy.

Beat in the egg until well combined.

Gradually add the flour mixture to the shortening mixture, alternating with the applesauce mixture.

Mix until just combined.

Fold in rolled oats and raisins or nuts (if using).

Drop by teaspoonfuls about 2 inches apart onto a greased cookie sheet.

Bake for 20 minutes, or until golden brown.

Let cookies cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
