I won't show videos of scary film clips to an unsuspecting audience (tick, tick, tick,...)
Fruitcake is the descendent of what was known as great cake in Shakespeare's time. It also is the traditional wedding cake. It went out of favor and was replaced with the tarted up birthday cake we associate with the bride upon the introduction of the home deep freezer in the mid 1950's. It left the culture about the same time the luxury liner did
Really good fruitcake is really good; even better is Jamaican Black Cake, but you can't serve that for breakfast unless you want the crew to go down for a morning nap. If you have a microwave in the office, you can bake your own muffins in a mug with or without raisins 'n' nuts or whatever you like in your muffin.
Here's a link to a microwave muesli muffin in a mug, which shsuit the techie, geekie gourmet's taste.
