I don't think so. No rice has to be brown and I have used ordinary white pudding rice. Going to make some rice pudd tomorrow with some coconut milk I have leftover mmmmm
And in answer to your other question all the major supermarkets will stock it. Usually found either with the other rice products or in the home-baking section (flour, icing etc). Failing that you can get away with using a risotto rice.
no i've never seen brown pud rice.i use broen or half n half sometimes for savoury and i just white long grain for pud too.i just cook in saucepan and then add a free yoghurt to it to make a free rice pud.yum!!!!
