I've investigated Naemanson's queries a bit further and it appears that what we call sultanas are known as golden raisins in the states. Candied peel is specified in a number of US fruit cake recipes I found so should be readily available.

Apparently the stirring should be from east to west, in honour of the three wise men.

Pudding basins with snap on lids are ideal. You can improvise with mixing bowls and the like but there's no substitute for the genuine article.

Good luck to anyone who tries the recipe.
