My idol, Peg Bracken (author of the 1960s bestseller The I Hate To Cook Book) suggested Irish Coffee as the all-purpose dessert. As she pointed out, by combining dessert, coffee, and after-dinner drinks, it saves remarkable wear-and-tear on the hostess. Of course, you can drink it just because you like it, too! If you turn on the coffee maker as you sit down to dinner, you can serve this quite quickly afterward.
