In a large bowl, cream together the butter and sugar until light and fluffy, about 5-7 minutes.
¾ cup unsalted butter, 1 cup light brown sugar
Add the egg, molasses, and vanilla, and mix well.
1 large egg, ¼ cup unsulfured molasses, 1 teaspoon vanilla extract
Then add the flour, ginger, baking soda, cornstarch, cinnamon, cloves and salt and mix until no dry streaks remain.
2 ¼ cups all-purpose flour, 2 teaspoons ground ginger, 1 teaspoon baking soda, 1 teaspoon cornstarch, 1 teaspoon ground cinnamon, ½ teaspoon ground cloves, ¼ teaspoon salt
Scoop into 2-tablespoon sized balls, then roll in granulated sugar. Place on a small baking sheet lined with parchment paper or plastic wrap. It’s ok if they're close together because you’re not baking them on this cookie sheet. Cover, and chill for at least 30 minutes to 1 hour.
¼ cup granulated sugar
Preheat the oven to 350°F, and place the dough balls 2-inches apart on a parchment lined baking sheet. Use the bottom of a drinking glass or ramekin to gently press down on the dough.
Bake for 9–11 minutes until the tops look set. Let the cookies sit on the cookie sheet for 5 minutes, then transfer to a wire rack to cool.
