I did the full Boxing Day with all the family at my folks' place. Drinking started early. By my calculations I got drunk three times and sobered up twice before collapsing into bed at some time after midnight and waking up the next morning feeling like death. I'd promised the wife I'd drive back, but literally couldn't do it (certainly not legally, anyway). She was unimpressed.
It is one of those meals that - enjoyed occasionally and when it's done right - is just one of the best things in the world.
It also demands to be eaten with the fingers, I find. a hunk of firm cod and crisp batter torn off with the fingers and shovelled unceremoniously into the gob is truly joyful.
