I have a corn intolerance where corn and corn byproducts trigger a migraine type headache.

I assume there must be corn byproducts in corn syrup because it absolutely triggers my corn reaction, but cane sugar does not.

Also from a purely taste standpoint there is a big difference to me as well.

Lastly, you can’t make peanut brittle chewy without corn syrup, with sugar alone (which is how I make it) it’s very crunchy.
