I read this about fruitcake storage. Interesting.
"after being slowly baked, the finished fruitcakes get their preservative treatment. Cheesecloth is soaked in brandy, bourbon, whiskey, rum or other liquor and then wrapped around the cooled fruitcake. The whole shebang is then wrapped in foil to ripen and age.
Fruitcakes soaked in liquor can literally last for years if you periodically add more liquor. Some fruitcake fans won't even touch a fruitcake until it has aged at least three years, although it's generally recommended that soaked fruitcakes be consumed within two years. Fruitcake should be tightly wrapped and stored in the refrigerator. Unwrap every few months and drizzle with liquor. Re-wrap tightly."
I wonder who originally thought of pickling a fruitcake in booze for storage?
