Cream together sugar, butter and shortening for 3 minutes.
Add the eggs, one at-a-time - mixing well after each egg.
Add the Anise Extract and mix well - about 1 minute.
In a separate bowl, combine the flour, salt, baking soda and baking powder and whisk together.
Add the dry ingredients all at once to the sugar mixture.
Beat just until the dry ingredients are incorporated into the wet ingredients.
*Add 1 T. of milk if the mixture is too dry*
This should make into a soft dough.
Separate the dough into thirds of fourths and roll into long ropes 2-3 inches across.
Wrap in plastic wrap and refrigerate at least 2 hours of overnight.
When ready to bake, preheat the oven to 350 degrees.
Take the dough ropes out of the fridge and cut into 1/2 inch thick slices.
Place on parchment lined cookie sheets.
Bake 10-12 minutes at 350 degrees until set and a little golden on the bottom.
Take out of the oven and place the cookies onto cooling racks.
Let cool completely, then ice.
