Salt the ribs and place in an oven dish, cover with foil and roast at 160 C for about an hour until tender.
Make the glaze by putting all the ingredients in a saucepan and heating. Stir until the sugar has dissolved and simmer until the mixture has reduced by half.
Remove the foil and pour off any moisture. Cover the ribs in half of the glaze and return to the oven at 200 C until golden.
