A common ingredient in the US, corn syrup is made by adding enzymes to corn starch, which turns it into a thick syrup of dextrose, maltose and/or glucose. It comes in two flavours – dark and light. Light corn syrup is very sweet, like golden syrup while dark corn syrup is similar in flavour to molasses. Corn syrup is used widely in the food industry for sweetening soft drinks, alcohol, ketchup and pickles.
