I went hunting recently for a tortiere recipe, this is an amalgamation of several recipes and my personal preferences to boot. And to add to the debate of what to serve with tortiere? My family likes HP sauce with theirs.
For the pastry you need a double-crust pie dough, chilled for an hour. I usually make the full block of shortening, and add an egg and a tablespoon of vinegar to my water, it makes an awesome crust. Even though I am now making dough enough for 3 double-crust pies that way. The rest I often turn into butter tarts or an apple pie, no one ever complains about that!
