I see people using gelatin all the time on their cakes. So why is it that when I put a gelatin piece on my MMF covered cake, that it start to melt almost immediately? It ran all down my cake and made a mess! It wasn't hot or even very warm in my house?
I won't be doing that again!

I'm curious to know the answer too!

What kind of piece was it? How long had the piece been made? Was the MMF fresh or did it set before you added the gelatin piece? Was there any shortning on the MMF?

I put gelatin on buttercream cakes all the time and have never had a problem - I don't understand how MMF could melt it??

Diane told us that if we were unsure if it would hold on whatever cake we were making, to make a gumpaste plaque to set the gelatin piece on so it won't come into contact with the cake surface.

Sorry you had a problem with it. icon_sad.gif

The gelatin was a thicker piece that I made the night before. The MMF was set and had been on the cake for at least 45mins to an hour before I put on the gelatin. I don't believe there was any shortening on the MMF either. I did a few other things and then when I turned the cake, I saw all this liquid running down my cake.....could it be because the gelatin was cold (out of the frig. for a few minutes) and it was like condensation happening? When I took the gelatin off, it wasn't wet to the touch. It was very strange!

IF you used the gelatin that you make into bows/butterflies etc. You CANNOT refrigerate it. The moisture in there will melt it - that is what the problem was. NEVER put the gelatin pieces in the frig or on a cold cake. Add them only after the cake is at room temp. ANY moisture (as in condensation from the cake coming to room temp) will melt the gelatin.

yes, I used the Knox. Lesson learned! Thanks Loucinda! I have left in on the counter in the past, and any that was left over sat out and grew some fuzzys, so I was concerned about that overnight. I didn't even think, 'cause it was so late.
so thanks again.

The gelatin will grow things if it isn't dried into a sheet - (if it is left in the thick state in a bowl) Once it has dried into the thin sheets - it will be fine, won't grow anything yucky then!
