Always make mine . I steam it in a steamer with a timer and just top up the water each time the timer pings. I have also done it in a slow cooker. The longer you steam it the more the flavour and the lovely dark colour develops. Wouldn't trust myself to microwave it. To those who can't believe that any one makes their own, it is so easy. All ingredients in a bowl, mix and cover then steam. I also make my own Christmas cake, mince pies , sausage rolls, stuffing, Tunis cake, chocolate log and shortbread. To be honest none of them take very long and they taste so much better.
