What is a reasonable temperature for slow cooked beef spareribs?
I wasn't intending to answer my own question, but there were no replies and so I went ahead with 24 hours at oven set to 80˚C (internal temperature is 74˚C which is lower than what I was expecting.

There is a little bit of water in the pan and the ribs are snugly wrapped in foil. They were rubbed in sugar, salt, smoked paprika, allspice and oregano/rosemary.
