commis,
good to see you posting.
i'd never come across it before.
i added in a tin of red kidney beans probably unforgivable but it worked a treat. i would try cooking in the oven next time or certainly for longer than the 2hrs (something like x2) as although the pork was cooked it was not as tender as it could be.
i did not have any of the orange and used my crushed red chillies in place of the specified. rest was to spec - even the 8 mins high heat on the pork browning worked a treat. well impressed.
