I found a nice recipe for a leg of lamb. It is however supposed to be baked for four hours.
It would be more practical for me if I could let it bake for 12 hours (overnight) -- would 12 hours vs. 4 hours be a problem?
I was planning to seal the pot and set the oven to 110°C (230°F)
EDIT: did it. 2 hours at 180C then 12 hours at 90C. The it was sealed with plastic foil (heat resistant) It was fantastic.
