Crunchy Honeycomb with Chocolate - Fail

Hi, sorry it's been forever since I've posted. It was finals week, blah blah blah, just didn't get the chance to post any of the recipes I've tested.
Anyway, long story short, I finally have time now!

Yesterday, I made the Honeycomb recipe. Unfortunately it didn't turn out the way it was supposed to... \:

Pros
+ color was similar to Sorted's
+ fizzing and bubbling was present
+ tasted good!

Cons
- didn't have castor sugar
- had to substitute Lyle's Golden Syrup with Karo Corn Syrup
- added honey
- probably added more sugar and syrup than I was supposed to..
- didn't harden
- stuck to the paper
- deflated a bit (is that supposed to happen?)

As for the sugar, I only had confectioner's sugar which, from online sources, is not the same as caster sugar. However, people suggested grinding up granulated sugar, which I did. Surprisingly, it actually worked! The sugar was half confectioner's and half grinded granulated sugar. Could that have been a problem?

WHY ISN'T THERE GOLDEN SYRUP IN THE US? I stood in the syrup section of a local Stater Bros. looking for a tin can that had a dead lion on it with bees surrounding it. No luck! I just had to settle for corn syrup. Isn't corn syrup supposed to be terrible for your body? Well, if anyone knows where I can get my hands on some Lyle's Golden Syrup, please let me know!

The color was looking a bit lighter than Sorted's so I added some honey. Being the genius that I am, I thought the honey could help with the color and taste. Wrong! It just made it more liquidy. So then I added more sugar which is probably the reason why it didn't harden.

Oh, and I left out the chocolate because I thought it would've been too sweet. ^u^

If ANYONE can help me out, that would be awesome! I would love to be able to make this treat to share with friends and family. Thanks! x
