ganache dripping down fondant cake

post #1 of 11
Thread Starter 
I attempted a fondant cake today with ganache covering the top and dripping down the sides. The ganache recipe was 8 oz. bittersweet chocolate and 8 oz. heavy cream. It seemed too thick and heavy. The "drips" weren't as skinny as I wanted them, and after a few hours the ganache on top started to crack and slide down the sides, like it couldn't support its own weight. Is the problem a too-slippery canvas (fondant) or a too-thick ganache? Any advice would be so appreciated.

I'd be interested to know the answer to that question too.

I have only used it on butter cream, I didn't think it would work on fondant.......good question

madgeowens, when you used it on buttercream, what ganache recipe did you use? Maybe my proportions weren't correct for the drippy look I'm after.

I just eye balled it...I put chocolate wafers in a double boiler and then added a couple tbs of heavy cream and stirred it until until it was the consistency I thought looked good and then I put it on the cake....its in my pics, its like a peach color cake

also, you may need more cream to thin it.....you don't want it real thick and you don't want it real runny....sorry I didn't use a recipe. Next time I will write it down.

I haven't covered a fondant cake with ganache, but the chocolate ganache 1 here on CC is great!

Well, let me preface this by saying that I've never pored ganache over fondant, but honestly, it sounds like your problem was with the ganache, and not the fondant/ganache combo. I really doubt that ganache would have any problems over fondant, but I could be totally wrong, lol! I do make a LOT of ganache pour cakes (over cream cheese and SMBC), and I'm big on details, so here's what works for me. YMMV

How warm/cool was the ganache? It doesn't matter too much what your cream to chocolate ratio is (well, it matters, but less than temp.), and for the record your's sounds like plenty of cream. The key to getting nice thin ganache drips is the temperature of the ganache when you pour it. It needs to be just right, and you'll probably need to do some experimenting to get it right... I don't think I can describe what the right consistency looks like... icon_confused.gif

Too cool/thick, and your ganache won't drip well. It will be clumpy, with wide, short drips. Sounds like what happened to you. Too warm/thin, and your ganache will pool right to the bottom of the cake, and you won't have any of those nice drips that stop half way down the side of the cake.

Finally, the method you use to pour the ganache on the cake can be really important to getting the nice, pretty, even drips. I do it two different ways, depending on the look I'm going for. I imagine there are many other ways... these are just the ones that work for me:

First, if I'm going for a drizzle over the edge look, I put thinned ganache into a piping bag with a med/sm round tip (6 maybe?) and just kind of zig zag the bag over the edge of the cake without stopping. I learned this from video posted by another CC'er but I can't find it, or remember who posted it. icon_rolleyes.gif

The other ganache dripping method I do (way more often), is where ganache is covering the whole top of the cake and dripping down the sides. I use a spreadable ganache recipe that's usually at room temp, and not at all pour-able; so I start by re-melting some ganache in an liquid measuring cup (I like the handle and pour spout). Not for too long either! Go in 10 second increments, stirring a lot between cycles.
Then pour a med-large puddle on the top of the cake. You do NOT want it to start pouring off the edge of the cake (that would be too much), but you want the puddle to be big enough that you don't need to pour more (if possible; cleaner lines with one pour). If I had to guess, I'd say I use about 3/4-1 cup ganache on an 8" cake? I never measure or pay attention though so that could be way off...

Then immediately grab a small spatula (I only use a tiny, round tipped, off-set) and start pushing the ganache over the edge a little at a time, in sections 3/4"-1 1/2" apart. Vary the amount of ganache that you push over the edge to get drips of different lengths. This way you'll have some ganache covering the top edge all the way around, but drips every 3/4"-1 1/2". Varying the length and spacing makes it look more random, like all you did was pour a bunch on and let gravity do the work. HA! icon_twisted.gif It's never that easy! icon_lol.gif But maybe I'm just a perfectionist... yeah. icon_rolleyes.gif

I always use ganache under my fondant and it works amazing. However, its 2 parts chocolate to 1 part cream. Thats is if you use 1 pound of chocolate (16 oz) use 8 oz of cream. Here is the info about ganache:
http://www.baking911.com/chocolate/ganache_truffles.htm..

When you make the ganache, let it set overnight (or atleast 6 hours before using on cake. Then When i put it on the cake then also i let it set for quite a few hours before putting fondant on. I spray the cake with water (not too much) and then put fondant on...HTH

Soygurl--your detailed instructions are excellent! Thank you so much. I will try a warmer ganache in hopes of getting thinner drips. I'm glad to hear that the fondant base probably isn't a problem. I'm practicing for a three tiered (non-stacked) wedding cake in a few weeks.
