In a large bowl, beat ¾ cup unsalted butter and ¾ cup light brown sugar until creamy, either by hand or with an electric mixer.
Add ¼ cup unsulphured molasses and 1 teaspoon vanilla extract. Mix.
Add 1 teaspoon ground ginger 1 teaspoon ground cinnamon ½ teaspoon ground allspice, 1 to 3 teaspoons minced fresh ginger, 8 ground fresh cardamom pods (if using ground cardamom, make sure it's very fresh), a pinch ground white pepper (optional) and ½ teaspoon coffee extract (optional) and mix well.
Sift the dry ingredients: 2 ½ cups all-purpose flour, 1 teaspoon baking soda and ¼ teaspoon salt. Add to the butter mixture in 2 or 3 additions. Mix well, but don't overmix (I recommend switching to a spatula). The dough will be shiny but not sticky.
Slice and bake: take a large piece of plastic wrap, place half of the cookie dough in the middle, make a rough cylinder, wrap the dough in the plastic, and roll it until it's tight. Prick in a few places to release air bubbles that might have formed. Repeat with the rest of the dough. Refrigerate the logs for at least 3 hours, or until firm. You can leave it refrigerated for a day or two. Or freeze for up to a month, wrapping the logs in aluminum on top of the plastic.
Scoop and bake: cover the bowl with plastic wrap and refrigerate for a few hours until firm enough to scoop.
Preheat oven to 350ºF (180°C).
Line a baking sheet with parchment paper.
Take out the dough from the fridge and put ½ cup additional white sugar, about ½ cup in a shallow bowl.
Roll the cylinder of dough, still wrapped, a few times on the counter to round out the parts that touched the refrigerator floor and are probably flattened. Cut the dough into ½ inch slices and coat each one with sugar. Alternatively, you can bake them plain, without rolling.
Or scoop small amounts of dough and roll in your hands to make walnut-sized balls. Do this quickly so the dough remains cold.
Arrange on the prepared baking sheet, leaving some space to grow between each cookie.
Bake for 10 to 12 minutes, until crackled and dry.
Let cool on wire rack. Store in an airtight metal container.
