I’d like to make a Saint Honoré for an upcoming party, and since there are so many components I’m curious about some of the timings / what can be done in advance. Which parts can I do ahead of time? I’m especially curious about how long the chiboust will ‘hold’ before being used (can I make it the night before and refrigerate it?), and how to store the assembled cake between when it is finished and when it will be eaten (which will be a few hours)
