I found this recipe in 'Joan Bishop's New Zealand Crockpot and Slow Cooker Cookbook'. This dessert is more like a baked pudding than a steamed one. It has a rich butterscotch sauce and is a good family pudding or to serve guests, especially in winter. It's also very easy to prepare. Definitely comfort food best served with vanilla ice cream or fresh cream. The author says to sit the pudding basin on a trivet in the slow cooker. If you don't have one of these she suggests using a metal jam lid or a metal biscuit cutter.
