Step 1
Heat lard in a large microwave-safe bowl until melted 30 seconds to 1 minute. Stir in boiling water.
Step 2
Combine flour and salt in a large bowl. Make a well in the center and pour in lard mixture. Mix with a wooden spoon until a smooth slightly sticky ball of dough forms.
Step 3
Dust a flat work surface with flour and knead dough for 2 minutes. Roll out 3/4 of the dough into a 1/3-inch thick circle. Press over the bottom and all the way up the sides of a 10-inch springform pan. Roll out remaining dough into a 1/3-inch thick circle for the top of the pie.
Step 4
Freeze pie crust base and top until firm about 10 minutes.
Step 5
Meanwhile combine ground sausage ground pork pork tenderloin onion parsley pepper thyme mixed herbs and curry powder in a large bowl. Mix into a paste.
Step 6
Preheat the oven to 375 degrees F (190 degrees C).
Step 7
Line the bottom and sides of the pastry crust with streaky bacon. Press in 1/2 of the pork mixture. Cover with 3 to 4 slices of streaky bacon. Press in remaining pork mixture; arrange remaining streaky bacon on top. Brush pastry rim with milk and add the top crust. Pinch the edges together to seal. Brush the top with milk and cut 2 slits in the top of the pie.
Step 8
Bake pie in the preheated oven for 1 hour. Reduce the oven temperature to 300 degrees F (150 degrees C) and bake until an instant-read thermometer inserted into the center reads at least 160 degrees F (71 degrees C) about 1 hour more.
Step 9
Cool pie completely before removing from the pan.
