Hi Lindsey, I'm thinking of making Delia's irresistible Christmas trifle (for the umpteenth Christmas!) for my family as it's unbeatable. This year though I'd like to ring the changes in presentation by serving it freestanding, held together within a "wall" of upright sponge fingers and made in a springform cake tin which I would release at the last moment - thoroughly chilled. Do you think this would be capable of sticking together like a cake....or should I stick to a decorative glass dish? I suppose one answer is to do a test run, ha ha....but you might be able to save me the effort! Thank you.
