The origin of the butter tart is not certain. Several origins are looked. I think it is nice there is both British and a French possible origin. It may originate with the Scottish Ecclefechan tart or the French tarte à la frangipane. It may date back to the 16th century. It certainly has become a widely enjoyed pastry treat in Canada along with other pastry treats more regionally identifiable, Nanaimo bars and beavertails.
In looking up a little more information about the butter tart I fond this article on a contest a few years ago, at Riverside Public School in my home town of Port Credit. I remember this school well down in the village by the river, for three years, (grades 7,8,9) I took dancing lessons there with many of the young people from different school. It was here that I learned the basics of many dances, ballroom and round dances. I also learned who to politely ask a girl to dance and afterwards to thank her and escort her off the floors. I think the teaching of manner was part of the motivation for the adults that organizes these lessons. They certainly came in handy in making all of us more comfortable with dances and partners in our teen age years. It was nice to see that small school was still being innovated with having students make butter tarts.
I have never made butter tarts myself. I have generally shied away from making pastry. I know it is more an art than a science. I would hate to do it badly and not up to my mother's standard. Maybe it is time to get over this and try to make some butter tarts, maybe even a blueberry pie?
