I have all said ingredients and I'm thinking crush ginger biscuits and layer them with whipped cream and rhubarb...
I'm sure I've seen this recipe somewhere (well, not really a recipe as no cooking required, more an assemblage) but I can't find it. Just wondering if there's more to it than that? Is there a subtle twist that will turn it from a strange collection of leftovers to a proper pudding that people will like and admire me for
