I know it's been suggested you can sub glycerine for corn syrup but I want to make Michelle Fosters fondant and it already has corn syrup in it (which I finaly found here yay! ) but I can't get hold of glycerine so can I just add extra corn syrup? If so what can I expect from the results of doing that??
Actually, you'd usually substitute corn syrup for glucose, not glycerine. Glucose is more like corn syrup without the water, so when substituting, you need to alter your wet ingredients to take that fact into account.
Glycerine is another "animal". It's an ingredient that helps retain moisture & keep the finished product soft. I can't really think of a true, edible substitute--sorry.

(Although I'm thinking human food grade would be a better choice.)
Okies, thanks guys, I have one more place to try and get it, if not I will add extra corn syrup and see what happens!
