Before anything, I want you to know we loved the cake very much. It is a good flavour mix between rose and elderflower. Thank you very much.
Now to give some advice please. I am a chef with Micheline star experience so any advice is from a professional perspective and to help you provide that enhanced experience I would love to receive for myself and my loved ones.
The cake didn't have that ring of flowers which you advertise in the presentation photo.
A smoother finish of the icing will put the cake in a higher class.
The flavours were not punching enough, it made me feel it was made many days ago. So a bit more essence of the elderflower and rose. And even though you know of the order many days before, try and don't do it too far ahead.
I could tell there was some syrup in the sponge, but the top 2 layers of sponge were dry, so the freshness effect was not there. Allow your stock syrup to reach a bit higher temperature to make it more viscous. This will help it lock in the sponge.
In description you say it will be delivered on dry ice. It was not. So if you can't always provide the dry ice, at least remove it from the description. If I'm not told of such, I won't expect it.

After all this, next year will order again. The cake it's a winner and executed nicely it can be amazing.
Thank you very much.

We absolutely loved the Elderflower and Rose Garden cake! Fresh, elegantly decorated and simply gorgeous! Thank you Patisserie Valerie 🩷
