Made with fresh ginger, bourbon, and molasses, this dark, spicy gingerbread cake pairs wonderfully with the light and creamy eggnog filling. This cake does need to chill for at least 8 hours, so make sure you plan ahead. Dust the top of this gingerbread cake roll with powdered sugar for an extra holiday touch. When it comes to your ginger, choose clean knobs of fresh ginger root with smooth, shiny skin. Store in the crisper drawer of the refrigerator and use it before it begins to shrivel. Remove the peel with a vegetable peeler or the tip of a metal spoon.
