Thank you very much Judy. They soak the rice much longer than I do so that may be the trick to get rid of the worst of it.
I didn't have anything in mind, I substitute black rice for white rice a great deal, the nutty flavour is wonderful. Also good if someone has a nut allergy and you don't want to lose the nutty flavour of a dish that should have them in.
When I have had Sid for a bit longer and have found some courage, I'll test cooking times.
Thanks again Judy for your help.
