"A glottally thickening wodge of chocolate chip and cocoa..." is how Nigella Lawson describes her chocolate gingerbread. It's an old-fashioned English gingerbread, moist and damp, cut into slabs as opposed to dainty chunks, and weighted with a hefty amount of cocoa.
It's also full of tiny chocolate nubs; to get these we recommend hacking up a good bar of chocolate instead of using more evenly proportioned chocolate chips.
It's topped off with a gooey icing of cocoa and ginger ale, which sounds odd but is heavenly.
For a late winter dose of heat and chocolate indulgence you really don't have to look any further than Chocolate Gingerbread. You can find the recipe at Nigella's website.
