I am not exactly sure of the origins of this drink. The recipe was given to me by a group of Canadians while I was bartending. Canadian visitors often asked for the drink and it became quite popular one summer with our locals. I have been told the recipe is also called a Canadian Ski Slope and have seen it called a Canadian Hangover , but the drink does not warrant the latter title as it rarely produces hangovers.... so the title Canadian Slipper from my worn, tattered and badly stained bar index card file will remain.....
