Well according to this article you can best use corn syrup, but you DO lose the flavor of the golden syrup. Which is why I recommended maple, because it suits the other flavors. However, according to the article corn syrup reacts the same way as golden syrup so therefore it would indeed be better.I just remembered. I saved a recipe for homemade Golden Syrup. I have not tried it yet.
I didn't know, because corn syrup is banned where I live. So I just use golden syrup and I know the flavor of maple and figured that goes well with my cake.
