Hi! I’ve been asked to do a cake with fresh raspberries and lemon curd as the filling. It’s a tiny cake, 6” and 4”.  Would it be best to do a layer of buttercream first, with the curd on top of that and the raspberries on top of the curd? Is it safe to make the day before or should it be assembled the day of because of the raspberries juicing? 

i would want to first talk them out of fresh raspberries -- i get a slice of vegan lemon cheesecake once in a while --sometimes with a raspberry on top -- the seeds are no fun and raspberries are tart -- 

if you assemble day of that's safer -- it has to be kept cold -- 

when i did fresh strawberry cake i encased the berries in well whipped whipped cream and it held great -- no leaky leaky

Also, keep in mind that raspberries MUST be washed before using. And that water will activate bacterial and especially mold activity instantly. I have seen mold growing in berries in matter of hours. Also washing will activate bleeding! I will never use fresh berries in a filling (none of them!). I always use them, by the tons as tarts, pies and cakes toppers, where you can monitor their "wellbeing!" I will use a thick layer of a yummy seedless raspberry jam instead... for safe keeping! Good luck!!!

ok -- wait -- it's the blackberries that have the giant seeds and are super tart! -- i happen to be eating a piece of that cheesecake right now and i was mistaken about the raspberries!!! sorry
