Hi, just thought I would add a little to what has been replied to already about the wires in cakes and wired sugar flowers etc as i'm from the UK and I know how differently things are done from country to country. its interesting to see how everyone does stuff.
In reply to tobeydechristopher i'm very happy to discuss how we make sugar flowers and display them here in the UK if you're interested. I am a UK cake maker and have just finished my professional diploma in sugar flowers.
In reply to it being good for them its good enough for us I guess it just comes down to what you are happy with and also your legal regulations may be different. in this country certain items are not allowed to be placed directly into a cake which is why we just use posy picks. To me if i received a cake that had a wire pushed directly into the edible part of the cake I wouldn't be happy. Who knows what may break off when you pull that wire out to cut the cake? Could you see a small piece of metal wire that may break off the end amongst a heap of fruit or a dark chocolate cake. I know I couldn't so that gets served to a young child and they choke on it? with a posy pick or similar device everything is contained within that pick. Its removed along with the wires stored safely inside before cutting the cake so you know your cake is safe.
the other issue that we look at in the UK is this - if you buy something from anywhere be it plastic, metal, wood or otherwise do you know where that has been before you put it in your cake. that item may have changed hands many times in a factory, sat in a warehouse, been touched so many times then it just gets pushed inside a cake with no thought for how food safe it is. All posy picks are food safe and you can get really tiny ones if you just want to put a single stem in the side of a cake. Larger posy picks also have serrated ends so they grip onto the cake and stop the things happening like large bunches of flowers tearing the side of the icing off.
If you want your wires to stick straight up you can use a larger gauge wire the same as those used for making sugar flowers. The lower the number (i.e. 22) the thicker the wire is.
Hope this helps shed some light on why in the UK we use these things and if anyone wants to ask any questions please feel free i'd love to hear from you here in the UK
