Corn syrup - ice shards

[Tinkerball]

I have a couple of Frozen cakes coming up and Im planning to decorate with "ice" shards dyed blue, all recipes online suggest using corn syrup. Obviously this is American and difficult to get hold of here, its on Ebay but very expensive! Someone suggested golden syrup, its not about taste but colour - I would think might not work as its darker colour to begin with. Found a tub of glucose syrup - do you think this would be suitable?

I've just tried HoneyDragon's recipe and it worked beautifully with liquid glucose - pale Aqua colour but looks very good.

(Then tried with golden syrup and it went green with blue gel food syrup, so not quite right - adding yellow food gel made it go sludgy!)

Going to try it tomorrow, have bought liquid glucose to.
