Corn syrup is very similar to glucose except corn syrup has a bit more water. Glycerine is different. It aids with stretchability and speed of drying of the fondant. Are you sure what you picked up at Michaels wasn't glusose?

You didn't pick up a container of glycerine if it listed corn syrup as the only ingredient. Glycerine list glycerine ONLY on the ingredient lable. I'd bet everything I have on that I imagine that you picked up glucose but I KNOW that it wasn't glycerine that you read the label on. Completely two different things. Absolutely NOT interchangeable.

Glycerine is just glycerine. Glucose is very simliar to corn syrup but much thicker. Go back to Michaels and read the glycerine lable. I guarantee it will say "glycerine" and ONLY glycerine.

You could leave it out but I find it really helps with workability. I even add it to my MMF now.

If you're making Michele Foster's Fondant it IS NOT ok to leave it out. It's an essential ingredient. So many times I see people post that a recipe "didn't turn out for them" then when ask some questions you find out that they left something out, added something, etc.

I suggest that you read her recipe all the way thru before you start making it. She says in her instructions that it's very important that the measurements be accurate on a few of the ingredients and glycerine is one of those ingredients.

Wilton's glucose comes in a tube like the piping gel. Their glycerine comes in a 2oz bottle like the flavoring bottles.

BTW there is no where in KayMc's post that states that she is making MFF. She might be making a completely different recipe. I have left the glycerine out from my recipe on occasion and it was fine. I just like the way it feels with the glycerine better.

She sent me a pm this morning. That's how I knew she was making MFF. I wouldn't have Just assumed that she was making MFF if I hadn't already known.

I am a professional pastry chef and was picking up some low temp molds at Michaels just yesterday and did the EXACT same thing; picked up a tub of glycerin and as I walked to the cashier with my purchases read the label:" same as the woman above, it was "corn syrup". 

 

I told the cashier I wasn't buying that item as I had enough at home and thought to myself that Wilton is marketing one of their products wrong. Which is strange because Wilton does make a veggie based glycerin. 

 

 

There are two types of glycerin (food grade is not used to make explosives, nor nitroglycerin mind you).

 

The difference is whether it's made w/ corn syrup or vegetable oil.

Glycerin

Glycerin for culinary use is a thick, clear, syrupy looking liquid used primarily in sweets to retain moisture and enhance sweetness. It is also used in candy making, such as fondant, to keep the candy from crystallizing.  The ingredient may also be used in royal icing to keep it from getting hard.
 

Food grade glycerin can be either animal or vegetable based and can be used interchangeably, depending on the grade.  The vegetable glycerin is typically made from coconut or palm oil while the animal derived counterpart is made from animal fats.  It is most common to use vegetable glycerin in food preparation.
