Method
- Spread the pumpkin puree in a thin layer over a double thickness of paper towels. Press more paper towels firmly on top, lift them away, and repeat with fresh towels until the paper comes away nearly dry. You should be left with roughly 1/2 cup of dense, dry puree. Do not rush this.
- In a medium bowl, whisk together the flour, cream of tartar, baking soda, 1 teaspoon cinnamon, ginger, nutmeg, and salt until evenly combined.
- In a large bowl, whisk the melted butter with 1 cup granulated sugar and the brown sugar until smooth and glossy, about 1 minute.
- Whisk in the egg yolk and vanilla, then the blotted pumpkin, beating until the mixture is uniform and no streaks remain.
- Add the dry ingredients to the wet and fold with a rubber spatula just until no dry flour is visible. The dough will be soft and slightly tacky. Do not overmix.
- Cover the bowl and chill in the refrigerator at least 30 minutes, or up to 24 hours. The dough must be firm enough to roll without sticking to your palms.
- Heat the oven to 350 F and line two baking sheets with parchment paper. Stir together the remaining 1/3 cup granulated sugar and 1 tablespoon cinnamon in a small shallow bowl.
- Scoop the dough into 1.5 tablespoon portions and roll each into a ball between your palms. Roll each ball generously in the cinnamon sugar, turning it two or three times so it is fully and heavily coated.
- Arrange the balls 2 inches apart on the prepared sheets, 12 per sheet. Do not flatten them.
- Bake one sheet at a time on the middle rack for 10 to 12 minutes, until the edges are set and the tops have cracked but the centers still look slightly underdone and puffy.
- Let the cookies rest on the hot baking sheet for 5 minutes. They will settle and firm into a chewy center with a crisp edge. Transfer to a wire rack to cool completely.
