Whisk the dry spices: In a medium mixing bowl, whisk together the all-purpose flour, ground ginger, cinnamon, ground cloves, nutmeg, baking soda, and fine sea salt until evenly dispersed. Set aside.

Cream the butter and sugars: In the bowl of a stand mixer fitted with the paddle attachment (or using a hand mixer), beat the softened butter, dark brown sugar, and granulated sugar together on medium-high speed for 2 to 3 minutes until light, fluffy, and well aerated.

Add wet ingredients: Beat in the egg, dark molasses, and vanilla extract until completely incorporated and smooth. Scrape down the sides and bottom of the bowl as needed.

Combine dough and chill: With the mixer on low speed, gradually add the dry spiced flour mixture in two batches, mixing just until combined and no dry flour streaks remain. Do not overmix. Cover the dough tightly and chill in the refrigerator for at least 45 to 60 minutes (this prevents excessive spreading and ensures thick, chewy centers).

Roll in sparkling sugar: Preheat oven to 350°F (175°C). Line two large baking sheets with parchment paper. Place turbinado coarse sugar in a shallow dish. Scoop 1.5-tablespoon mounds of chilled dough, roll between your palms into smooth balls, then roll thoroughly in the sparkling sugar to coat completely.

Bake to chewy perfection: Space dough balls 2 inches apart on the baking sheets. Bake at 350°F (175°C) for 9 to 11 minutes. The cookies will puff up, develop beautiful crinkly fissures, and look slightly underbaked in the center. Remove from oven and let sit on the baking sheet for 5 minutes to set, then transfer to a wire rack to cool completely.
