I would love to make lamb kleftiko Witzend , where did you find your recipe please?
There are a lot of recipes online, if you google.
They varied a lot! Some added sundry spices, e.g cinnamon, which I didn’t fancy at all.
But the methods were all much the same.
FWIW I marinated mine, in the fridge for 24 hours, in olive oil, chopped parsley and mint (I’d use more mint another time) dried oregano, lemon juice and a little salt. The recipe said to stab little holes in the meat and rub the marinade in.
You then wrap it in a secure parcel using first 2 pieces of baking paper, one lengthways, one crossways, repeat with 2 pieces of foil, make sure it’s well sealed.
Put in an ovenproof dish.
Mine (a half boned shoulder) went in the oven for at least 4 hours at around 140 fan, after which I dropped it to IIRC 130 for a couple more. Parcel stayed intact with all the juices - the meat just fell apart.
I cooked potatoes separately, but some recipes include them.
