Stir flour, salt & sugar together. Work shortening of choice into flour, mix the eggs in and add as much additional ice water as needed so that the dough comes together.
Divide part ¾ of the dough into a flat disc, do the same with the other ¼, wrap in saran and refrigerate for at least 1 hour.
Use an 9 or 10 inch inch springform pan, using the larger amount of dough for bottom & sides, ¼ for the top.
Fill with the cheese/meat mixture, but don’t pack or compress it, nevertheless making sure that there are no air bubbles in the filling.
Bake at 350 degrees for 1½ hours.
