Preheat oven to 375°F (190°C).

In a large bowl, cream together the softened butter and sugar until light and fluffy.

Beat in the molasses and egg until well combined.

In a separate bowl, whisk together the flour, baking soda, clove, ginger, cinnamon, and salt.

Gradually add the dry ingredients to the wet ingredients, mixing until just combined.

Stir in the chocolate chips or raisins, if desired.

Drop by teaspoonfuls onto an ungreased cookie sheet.

Bake for 8-10 minutes, or until the edges are lightly golden.

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