Ok, so I'm right in the middle of doing this cake, planning to use blue colored piping gel to make a small pond. Go to find my piping gel and I'm out! So, can I use clear corn syrup on a cake and it give the same type of effect? Don't have time to get some piping gel or make some. Please help!!! Thanks!!
Yes! I did it last week when my order got shorted the piping gel.
For some reason when I used it as dripping blood on a fondant covered cake the fondant cracked where the corn syrup was. My fondant was satin ice.
Corn syrup has a lot more water in it than piping gel. If it sits on the cake for any amount of time, it could weaken and/or melt the fondant.
If I were going to use it on top of fondant, I'd put a layer of buttercream (crisco based) under it first. I think that would provide enough of a waterproof barrier until the cake was delivered and served.
