Step 1: Preheat oven to 325F. Line a 9x13 cake pan with aluminium foil and grease it, or grease a foil tray of the same size.
Step 2: Put the butter, syrup, dark brown sugar, stout, ginger, cinnamon and ground cloves into a pan and melt gently over a low heat.
Step 3: Remove from heat and whisk in the flour and baking soda. Whisk thoroughly until there are no lumps, this may take some time.
Step 4: In a small bowl, whisk the sour cream and eggs. Beat into the gingerbread mixture, whisking again to get a smooth batter.
Step 5: Pour the batter into the prepared cake pan and bake for about 45 minutes; when it's ready it will be "gleamingly risen" at the center, and pulling away from the sides of the pan.
Step 6: Let the gingerbread cool completely, then cut into slices or squares.
