I'm doing a cake similar to this for a wedding in November.  The cake has to travel about 45 minutes through hilly, curvy, bumpy country roads.  Normally I would attach the petals with edible glue but I'm afraid that won't be strong enough.  Will white chocolate be better?  Will white chocolate end up being too heavy?

Also, I can't tell from this picture and the bride to be hasn't gotten back to me yet but is that a flower on the top tier, with petals coming out from it?  Or is it just all petals?

hi,

i think you should use edible glue to stick on the petals, then when the glue drys put 2 small drops of white chocolate on the bottom of the petals.

FYI i did this on a cake that i had to take 4 hours away so trust me :)

Hope i could help, Jellybeanking

ATylose glue is plenty. Nothing else needed.

I was on my phone before - just wanted to add, bring some extra petals or (equipment to make them) and some glue for any repairs just in case. But in my expereince they are rarely needed.

I'm with Howsweet...I just did a petal cake last week and a wee bit of tylose glue will make those petals stick to your fondant-covered cake like superglue.  I didn't lose a single petal.  For me, keeping white chocolate at a perfect piping temp (without it cooling and hardening at the tip of the piping bag repeatedly) throughout all of the time it will take you to make those petals would be a PITA.  That's just my opinion, though.

I would cut and ruffle about 15 petals at a time and then glue and stick.  This gives the petals time to stiffen up a bit and hold their shape but still be pliable enough to get them positioned perfectly.  

Hi,

With a fondant cake and petals, royal icing is the best choice and it will set really firm if left overnight so no problem travelling with it.

Good luck
