I'll try and answer some of your comments with my observations:
Cooking temperature was fine at 180c for a 2 hour cook. You could lower the temperature but would have to increase the cooking to 3 hours.
The water/sauce was a master pierce. Tightly packed in foil, the juices from the lamb and extra garlic butter, have no where to go other than to find a route out of the foil. This may have something to do with the higher oven temp too. The water prevents the juices burning when they hit the roasting pan. At the end of cooking, your left with a perfect jus to pour over the succulent meat. You need to keep an eye on the amount of water keeping it topped up if necessary. I also rung out the foil to extract as much juice from them.
If your not too keen on garlic you could leave out the fresh garlic and just use the butter. I used plain Garlic Butter (Lurpack) but he used Garlic & Herb Butter which is generally a mix of Basil, Chives & Parsley.
The critical element to this dish has to be the oregano and the bay leaves. I used fresh Bay leaves picked from the garden and used dried Wild Oregano (Tesco). The oregano worked well and didn't over power the dish as I had feared it might.
Two schools of thought moving forward:
1. Use a different bone in cut like a leg steak to create individual parcels as seen in the first linked video. Adding the garlic and herbs as I did for the one I made, but with the addition of a drop of white wine to provide the jus.
2. Use shanks again but straight in the roasting pan and nestled with extra
veg.to make a snug fit. A couple of glugs of white wine and foil over the top.
I think this is a forgiving dish that can be 'messed' around with, or left fairly rustic with 'basic' ingredients, such as the first video. I generally like rustic foods so will definitely be trying the other one.
Reading up on Afelia suggests that the main difference apart from being pork, is the cooking method. Kelftico is baked, whereas Afelia is braised in red wine.
Talking of Pork, did you see the Pirgos?
