Step 1: In a large mixing bowl, cream shortening and sugar. Add egg; mix well.
Step 2: Dissolve baking soda in hot water; stir into sugar mixture. Stir in sour cream and vanilla.
Step 3: Add flour, baking powder, and salt; mix well. Cover and chill for at least 2 hours.
Step 4: Preheat oven to 350F (180C or gas mark 4).
Step 5: Lightly grease or line cookie sheets with parchment paper. (I buy parchment in bulk from the local food service store - a great price and less grease and clean-up).
Step 6: On a lightly floured surface, roll dough to desired thickness (1/8-inch for crispy and 1/4-inch for softer cookies). Place cookies on prepared pan.
Step 7: Optional - sprinkle cookies at this point with colored sugar, or, to make cookies to frost, leave them plain.
Step 8: Bake cookies for 10-12 minutes, until edges are lightly brown. Cool on racks. Decorate when cooled with your favorite frosting and decorative candies. This recipe works well for any holiday!
