Start by thawing your Wicks' pie crust shells, and dough circles. Remove from the freezer, and bring gently to room temperature.
Pre-heat oven to 350℉
Thinly cut beef into bite-sized slices. Place in a saucepan, and add enough water to cover. Bring to a low boil, simmering gently for 30 minutes.
Meanwhile, chop ham into small cubes, and add to a large heat-proof bowl.
When the beef has finished simmering, remove the slices from the pot, reserving the liquid it's been simmering in. Add beef to ham, and toss to mix evenly.
Divide the ham and beef between the three pie shells.
In a small dish, whisk the ¼ flour with just enough water to thoroughly blend to a thin paste, making sure there aren't any lumps. Slowly add to the reserved beef broth, whisking constantly until it's thoroughly whisked in.
Bring liquid back to a gentle simmer, stirring until thickened. Add butter, salt, pepper, and ground cloves. Then adjust seasoning to taste, adding a little additional salt or pepper if desired.
Add thickened gravy to the pies, filling to just below the rim of the crust.
Place dough circles in place, gently sealing the circles to the bottom edge of the crust, and crimping with fingers or a fork. Add a few slits or cuts to the upper crust, to allow steam to vent, and decorate the crust if you like.
To give the crust a golden, glossy finish: blend an egg yolk with 1 tablespoon water, then brush onto the crust thinly with a pastry brush.
Place pies in oven, with a baking tray underneath to catch any gravy that might escape. Bake 40-50 minutes, until crust is golden brown, and gravy is bubbling through slits in the crust.
Remove from the oven, and allow to cool slightly before serving.
