There really isn't a regional sauce in Alberta, Canada, I'm sad to say. The only thing close to a regional sauce would be the store-bought commercial sauces. That would be Kraft, Bullseye, Heinz and Cattleman's, in order of popularity.
However, on the bright side, I make a lot of the sauces from Sauces, Rubs and Marinades
, and what's more is I can them for later use. I often do this in the dead of winter when it's too nasty and cold to do much else.
