From the IP, I usually make a "wet" dish, so it's sort of braised in this case, although it could be done on a trivet and finished in the oven oe a quick sear on the BBQ.
When I slow roast it, I just heat the oven to a hot setting 200c or 220c, but as soon as I put the meat in, it is turned down to 150c and left to it's devices for at least 3 hours, although often more like 4. The meat and fat rises up, from the bone, to become quite tall really, but much taller than they start. Yummmmmmm.
If I think I'll fancy something with a bit of a different flavour, I'll put them in a dry rub and marinade it that way overnight/24 hours or if I vacuum seal the dry rubbed meat, a few days in the fridge, then slow roast as above.
The most delicious of all I have never, ever been able to recreate - mainly as the dry rub was stored in a small clip-top box which I had neglected to label. It was a home made rub, but no idea what I had used it on before.
Cooking can be one of life's adventures in this hacienda, but nobody died,...............yet! The short ribs with balsamic onions was probably a close run thing though. It wasn't my finest hour, and the annoying thing is I had followed the recipe. I hadn't freestyled even a little bit!
