Preheat oven to 350º.
Combine shortening, granulated sugar, and eggs in a mixing bowl and mix with an electric mixer until thoroughly mixed.
Add orange rind, lemon extract and baking powder and mix again with an electric mixer being sure to work all the baking powder into all areas of the dough.
Add half and half and cream the ingredients with the electric mixer until fluffy.
(I added it slowly to avoid spatters).
Stir in flour until the dough is very well mixed.
Chill dough at least one hour so it’s easier to handle.
Remove bowl of dough from refrigerator.
Place powdered sugar in a small mixing bowl.
Pinch off golf-ball sized pieces of dough.
Roll dough into balls; then roll the dough into powdered sugar.
Place balls on greased baking sheets leaving room so the balls aren’t crowded.
Bake approximately 10-12 minutes or until done.
Rotate cookie sheets on oven racks after eight minutes of baking time.
