Mix together the flour and salt in a large mixing bowl.
In a second large mixing bowl, break up the lard into chunks using a spatula or wooden spoon.
Pour the boiling water over the lard and stir until the lard has completely melted.
Add the flour and salt to the lard, and stir well until the dough is fully even and incorporated leaving no pockets of dry flour.
Cover the bowl with kitchen wrap and refrigerate for 8 hours or overnight.
To make the pasty filling
Add all the diced vegetables to a large bowl. Crumble up the ground beef and add it to the vegatable mixture.
Add all the remaining seasonings to the mixture and stir well so everything is evenly distributed.
Pasty assembly
Preheat an oven to 350ºF.
Divide the doiugh into 8 equal pieces. Use a kitchan scale to help with this. Roll into a smoth ball.
On a well floured work surface roll out each ball into an 8 inch circle about 1/8" thick.
Spoon approx 1/8 of the mixture onto one half of a pastry circle leaving a 1/2' clear around the edge for sealing. Top the mixture with 1 tbsp of butter. Moisten the edge of the pastry and then fold the other half over and press down. Crimp with a fork to seal.
Transfer to a parchment lined baking tray. Repeat with the remaining 7 pastry balls.
Bake for 1 hour, until the pastys are a golden brown. If they brown too quickly, cover with aluminum foil.
When cooked, transfer to a wire rack. Melt 4 tbsp of butter to brush the tops of the pastys as they cool.
