In a medium bowl, pour 2 cups of warm water over the raisins. Let them soak for about 10-15 minutes until plump.
Preheat your oven to 350°F (175°C). Line your baking sheet with parchment paper.
In a large mixing bowl, whisk together the all-purpose flour, sugar, baking soda, baking powder, salt, cinnamon, nutmeg, and cloves.
Cream the vegetable shortening in another bowl until smooth.
Add the slightly beaten eggs to the creamed shortening and mix until well combined.
Strain the soaked raisins and fold them into the wet mixture. Gradually add the dry ingredients, stirring gently until just combined. Avoid overmixing.
Fold in the coarsely chopped walnuts, ensuring even distribution throughout the dough.
Using a tablespoon or cookie scoop, drop dough onto the prepared baking sheet, leaving space between each cookie. Bake for 12-15 minutes until edges are golden brown.
While baking, whisk together powdered sugar and 3 tablespoons warm water until smooth to make the icing.
Allow cookies to cool on the baking sheet for a few minutes, then transfer to a wire rack. Once completely cool, drizzle the icing over the cookies.
