Wassail

It occurred to me that I hadn't looked up Wassail, so I set out to do so, and got overwhelmed in the world of Wiki, never a good place to be really, keeping in mind at the end that wiki is not always accurate in information...
But it appears there is wassailing - some sort of ceremony of wishing good health to an apple tree with mulled cider, to ensure good harvest (and therefore more cider!), done at old twelth night - 17th Jan.
There is also caroling wassailing - singing Christmas Carols in exchange for treats/presumably including something to drink, which used to be done as a gift exchange between the wealthy and the poor as a non-begging charitable gift giving exercise.
Wassail the drink, mulled cider, appears to accompany orchard wassailing, which apparently still occurs in big apple growing areas in Britain today!
The wassail I had when we went caroling was based on cranberries, and must be a local (Ocean Spray...) adaptation.
