I wouldn't use corn syrup as a substitute for Golden Syrup though. Pour it on pancakes, anyone?

I couldn't imagine pouring Golden Syrup on pancakes, but Americans use corn syrup on their pancakes all the time. Check out the ingredient list at this link:

Not my choice, a parental choice and also I think not only was real maple syrup expensive, it was becoming rare. I also remember having plain old Karo syrup on my pancakes (yuck!! - TOO sweet).
Even though it's still extremely expensive, I prefer using real maple syrup - just bought a small bottle at Tesco the other day for £4+ (cringe!). When I visit the US, I get the chance to use stuff my brother has made from his own maple trees...
