Mix the flour, salt, sugar, butter and 6 Tablespoons shortening together with a fork or your hands. Add the water in increments until a smooth dough results.
Roll the dough out to 1/4" thickness and cut into 4x6" rectangles.
Spread strawberry jam onto a rectangle of dough, avoiding the edges by 1/2". Place another rectangle overtop and press the edges together with your fingers or a fork.
