what can I use for glucose and glycerine in the fondant recipes if I cannot find them? Knox is generally easy to find, but the others...
my first thought is that glucose is sugar, so either regular or powdered sugar, but glycerine?

Glucose sub would be corn syrup not sugars.

Not sure if there is a sub for glycerin. Have you tried getting some at a pharmacy?

Krystl,
You are correct; glucose is a sugarâ¦one of many different sugars. It is not the same as granulated sugar.

If this is your first time making rolled fondant, you may want to try the marshmallow fondant recipe. The marshmallows already come loaded with most of the âchemicalsâ that you need for rolled fondant.

If you want to stick with gelatin-based rolled fondants, you can substitute Karo light corn syrup for the glucose. You will need to watch the water balance (add more powered sugar or add less water), since containers labeled âglucoseâ typically have less water than containers labeled âcorn syrupâ

Food-grade glycerin gives the fondant more flexibility and makes it less likely to crack or get 'elephant skin'. Having said that, some people have good results without adding glycerin.

I have read that liquid vegetable oil can be a compromise substitute for the glycerin in rolled fondant. Shortenings loaded with emulsifiers also help improve flexibility and discourage cracking. Be careful and do not add too much or you will create another set of problems.

Good luck!

DO the marshmallow....you may never want to try anything else.

I now make marshmallow fondant and want use anything else. Way easier to make. And you can buy your ingredients at the grocery store.
