Sift the flour and salt together in a medium-sized mixing bowl.
Put in a saucepan the milk, water and the lard; bring to a boil, and pour into the bowl with the flour. Mix until a dough forms (don't worry about it being smooth yet.)
Let stand until cool enough to handle, then turn out onto a worksurface, lightly flour, and knead until you have a smooth dough. If it seems crumbly, add a bit more hot water.
Mould into the standing shape you need, or line a mould with it.
If you are going to be a while working with it, or will making making several small standing pies, you need to keep the dough warm.You can do so by putting it on a plate over top a pot of simmering water.
