Award-Winning Butter Tarts from Food.com: Butter tarts are a Canadian tradition. Waaaay back in the 1970s, a national contest here in Canada concluded that these butter tarts, originating from Wilkie's Bakery in Orillia, Ontario, were the best. Add a sprinkle of toasted walnuts when you add the raisins, if you wish, or use only walnuts if you don't like raisins.
The Best Classic Canadian Butter Tarts - there's a reason why we have a national obsession with these sweet, buttery, caramel-y tarts. I've sampled them in many places across the country and this thick pastry version is my favorite. Don't do the raisin debate, just leave them out if they are not your thing. Everyone should be able to enjoy them as they like them.
