Place the water and lard in a small pot over low heat. Melt shortening (or butter or lard) into the water, but DO NOT BOIL.
In a deep mixing bowl, add the flour, salt, and melted lard/water. Mix until combined. Once it’s cool enough to handle, work with your hands into a ball shape. Flour a surface and continue kneading for about a minute.
Divide pastry into equal parts depending on the tins you’re using. Grease your tins. Roll out pastry into disks and place into tins so that it comes all the way up the sides. Cut off any overhand with a knife if needed.
Refrigerate at least an hour, ideally overnight.
