Trim the membranes off the meat, wash it, then salt it and leave for 15-20 minutes.
Put the meat in the roasting tin with the fattier, more sinewy side on top.
Dust it thinly with flour, then evenly with paprika, and add the fat and 200 ml of water alongside.
Put it in an oven preheated to 200 °C and roast for 20 minutes until the surface sets.
Then turn the temperature down to 180 °C and roast for another 1-1.5 hours, basting with its own juices every 15-20 minutes and topping up with water if needed.
Towards the end, when the meat is tender (easily pierced with a skewer) and the top is nicely crisp and reddish brown, take it out of the oven.
Strain the fat from the tin, then make a brown gravy from the remaining juices by boiling them with water and scraping up the browned bits.
Serve the meat in thin slices with the gravy poured over, with sides and salad.
