I know that I am making this easy trifle way too complicated, but I have never made it and am doing it for a lunch show today, so want to be sure I look like I know what I'm doing! I have seen 2 different versions of this recipe, one calls for one chocolate bar and the other calls for 3 heath bars. How do you crush it for the layers. Will the rotary grinder work on a heath bar or do I need to smash it with something? I should've just bought the ones that are already crushed, but was thinking that I could demo the rotary grinder for something other than cheese for a change. Will it work? And should I make the pudding up ahead of time (before I go to the show) since I will be doing this at a business with no fridge? And do you do the cool whip with the easy accent decorator or just scoop it in? So many questions! Sorry! and TIA!
