brown sugar, champagne yeast and a pinch of baking soda in initially warm water works the best. slow to get going and sometimes an extra later shake is required but it lasts twice as long and is far more regular than white sugar with bread yeast. the only problem is champagne yeast is a whopping 75p more expensive and brown sugar 25p more. check with your accountant before you make the switch.
