Wafer thin and crisp, these old-fashioned Gingersnaps are flavored with ginger, cinnamon, and cloves. Good spicy warmth of the wonderful tastes and scents of the Christmas season. A holiday classic!
Into medium-sized saucepan, combine molasses, brown sugar, and butter or shortening. Over medium-low heat, bring mixture to a boil, stirring regularly to prevent scorching.
Remove from heat. Add soda and stir well. Cool mixture to room temperature.
Add egg yolk to cooled mixture. Stir well.
Sift dry ingredients into a bowl and mix into wet ingredients to make a stiff dough. Stir well to combine.
Turn dough onto wax paper and roll and shape into two logs each about 2½” - 3” in diameter. Wrap each roll individually in plastic wrap. Chill for 24 hours.
Preheat oven to 375F. Remove cookie logs from refrigerator and unwrap. Using a very sharp knife, slice each log into 1/8” slices and place about 1” apart on parchment-lined baking sheet.
Bake for 10-12 minutes. Let cookies cool on pan for 2-3 minutes then transfer to wire rack to finish cooling.
