I don't know, corn syrup is something that is very unique in taste. Although I cannot normally taste any difference in food stuffs, Kraft M&C, Cheerios, etc, between the US and UK versions, I can taste the difference if has corn syrup or not.
Don't get me wrong, your pecan pies will be most edible with golden syrup, it just won't be mom's (well my mom's). And popcorn balls will never taste the same as the ones I grew up with, unless I splurge for some Karo. Incidentally does anyone know what is the price for a bottle of Karo in the US? The last time I brought Karo Syrup here, it was about £4 for a bottle.
Interesting discovery we made on holiday this spring regarding corn syrup.
Me, DS, DD & DDBF were traveling in the US and it dawned on us that DD & I had the same preference for candy whereas DS & DDBF had a different preference altogether with no overlap of mine & DD's preference. We started to analyse this (long road trips LOL) and discovered two things:
All the candy that DS &DDBF did not like were all corn syrup based.
Both DS &DDBF absolute hate honey
How these two relate, I don't know but we discovered later a cousin that was the same, didn't like certain candies (corn syrup based) AND he couldn't stand honey. Anyone else ever experience this?
But I do think corn syrup is subtly very unique. I believe someone in another thread pointed out the difference between coke here and the US is that the US coke contains corn syrup.
