How to Cover a Cake in Ganache


 Some bakers actually 'ice' their cakes with chocolate ganache in lieu of buttercream.

Why?

Well, aside from tasting like chocolate truffle filling, ganache can have much more structural integrity than buttercream.  It is easier to get sharp corners and smoothness by using a hot knife, has no air bubbles, and best of all... WON'T BULGE!!! :)  That's right, ganache can withstand the added weight of fondant much better than most buttercreams.

I got the idea from this book:
Planet Cake isn't one of the books I use all the time, but has some nice clean, simple ideas, as well as ganache recipes and instructions for covering a cake in ganache.  
So I made an 8" round chocolate cake which I filled with chocolate mousse.  I'll post about chocolate mousse another time after I actually figure out how it's supposed to work. :)  It tasted good though!  

Since the cake was already stocked with dark chocolate a plenty, I made a white chocolate ganache to cover the cake. 


I started with 1.5 lbs of white chocolate, and added 8 oz of cream.  I melted everything in the microwave, stirring every minute or so.  After letting it stand (covered) for 5 mins, I whisked the ganache and let it set up over night.  Before spreading it on the cake, I microwaved it again for about 15-20 seconds.












After covering the cake, I smoothed it out using a hot spatula.


 I'm trying to rig a level or levels to my bench scraper so that I can get perfectly vertical sides... yes, I'm that OCD.  I'll let you know how it goes.

Anyway, I let the ganache set up in the fridge for a bit and then covered the cake in fondant. 


By the way, my fondant rolling pin is a 2 ft length of PVC pipe.

What follows is called tip 1, tip 1.5, and a small leaf tip, some black royal icing, and no plan. :)




In the future, I should probably come up with a plan, but it was fun to just practice some piping.
Oh and the cake?  Delicious.  :)

Elegant Square Cake


At Georgia Tech, we're mostly engineers, and there aren't too many women around.  So, in the Mechanical Engineering department, we have a graduate women group to help us meet the other women in the department, and we do a lot of social events and seminars and lunches. :)

Last week, we brought in a female Ph.D. from Sandia to give a talk and meet and mingle with students and faculty at Georgia Tech.  After her talk, we had an informal lunch where the other women grad students could ask questions.  Long intro, but I was asked to bring a cake for the lunch.


To spice things up a bit, I made my first square cake!  The cake was a yellow cake with a ganache filling.  The ganache was garnished with fresh, sugared strawberries.  The outside was covered in standard vanilla buttercream, then I covered the cake in fondant.

I am happy to say that my fondant rolling skills are getting much better-- I actually covered this cake in one shot and in a reasonable amount of time!  No wrist cramps from rolling!  I guess my PVC pipe rolling pin is working out. :)



I cut out a light gold ribbon (Tech's colors are white and gold), and added the gold bow.  I used some tissue to help the bow hold its shape while drying.  Then, I piped a white swirling pattern over the rest of the cake.

The bow, up close, while drying.


The pattern ended up being a little smaller and more intricate than I was planning, so it took a little longer, but overall, this cake went very smoothly.  Oh, and the taste got rave reviews, so that makes me happy.  I'm paranoid about my cakes tasting bad or being dry. 



On an unrelated note, I start Wilton Course 3 this week-- yay!  First class is on Thursday.

Also, for the summer, I'm considering applying to be a home based business, so that I could legitimately take on some cake orders on the side... Still figuring out what all is entailed, though.  Every state/ county is different. 

Have a great week, everyone!

Happy Valentine's Cake


What did I do with my snowy days down here in Atlanta?  Made a cake, of course!

The inspiration for this cake is definitely Margaret Braun.  I'm sure I've mentioned her before-- she's the 'daintier' of the two female judges on TLC's Ultimate Cake-Off and is a world renowned cake artist and author of Cakewalk.  In one of the older Ultimate Cake-Off episodes, they bring in a cake that Margaret piped and ask the competitors to pipe a similar cake in only 15 minutes.  My goal in making this cake was to create something similar (from what I could remember).  Of course, I took longer than 15 minutes. :)

Starting with the cake itself, I decided to try a red velvet cake.  I used a recipe from Rose's Heavenly Cakes by Rose Levy Beranbaum, author of The Cake Bible.  The first notable characteristic of this recipe was that it called for 1 BOTTLE of red food coloring...  There was no mistaking its color.


Another interesting characteristic of this recipe was that it was supposed to make either a 9" heart or a 9x2" round.  ONE 9x2" round.  However, when I was making this recipe I tried to weigh my dry ingredients.  However, all I own is a cheap, non-digital, grocery store brand scale, which I now realize tends to underestimate.  As a result, I think I ended up with a little more batter than the ever-so-meticulous Rose...

Have I mentioned that I am actually not nearly as big a fan of the actual baking as I am of decorating?  I like cooking-- it's much less precise and more forgiving.  In particular, I like to cook by feel-- no recipe.  Baking is so scientific.  I guess I should prefer that approach since I'm an engineer, but I guess I'm more interested in the artistry of decorating.  I do enough technical stuff...  That said, I want to make sure my cakes are delicious, so I do the whole baking thing. ;)

Anyway, I ran the numbers and decided that 1 9x2" round was roughly equivalent to 2 6x2" rounds.  Now that I'm actually paying attention to the numbers, I guess the 2 6" pans less volume than the 1 9" round...  Anyway, I chose to use 2 6" rounds and didn't bother to use any less batter than what I had prepared, since the pans only seemed to be a little less than 2/3 full.  However, the batter rose quite a bit.  Nothing overflowed, thankfully, but I think I need to err on the side of caution when filling my pans.

No mistaking what color this velvet is...

To stack the cakes, I trimmed off the tops that mushroomed over the pans, and then torted them with a cake leveler.


I filled the layers with chocolate ganache, using plain buttercream as a barrier.

 
Mmmmm.... Ganache...



After stacking all four layers, I iced the outside of the cake with another Rose recipe: Dreamy White Chocolate Cream Cheese Icing.

 

This icing recipe is drastically different from what I've really worked with in the past (though it's very tasty).  Because it has a high concentration of chocolate, it dried VERY hard in the fridge.  It actually cracked in spots.  Before I covered this cake in fondant, I went over it and filled in the cracks and re-smoothed with a very very thin layer of buttercream.

Covering with fondant was again a challenge.  This time, as a new challenge, I colored the fondant that peachy-pink color.  I used the dough hook on my kitchen aid to knead the fondant and knead in the color.  This helped soften the fondant significantly, but did create some air bubbles.

I had an easier time rolling, but had a rough time with cracking and tearing.  It took me two attempts to get the cake covered, and because of the cake's aspect ratio, it was very hard to smooth.  Imagine a tablecloth: the wrinkles have to go somewhere.  I started smoothing sideways, and this was a mistake, because I ended up with wrinkles that had nowhere to go.  Ultimately, I made some compromises and got it covered, but it had obvious imperfections.  Fortunately, I'm taking a beginning fondant class in early march and can hopefully pick up some pointers.  I think I need to elevate the cake, but I was afraid of making this cake topple off of something that wasn't designed to support a small diameter cake.  

Then comes the fun part-- royal icing piping. 


I started with the only detail I really remembered from the Ultimate Cake Off cake-- the swags.  These swags are described in Margaret's book, too.

It's interesting to read the literature of different cake artists-- they all have their own signature repertoire and idiosyncrasies... and things they feel strongly about.  For example, Margaret Braun says in her book that airbrushes are for T-shirts and vans, and that cakes ought to be painted.  Sylvia Weinstock seems to think that fondant is the most vile stuff on the planet and she'd never serve it to her guests, so she won't use it on her cakes.

Anyway, back to Margaret's piping.  She is known for her piping skills, but as I look through the cakes in Cakewalk, it's clear that she has a reasonable sized repertoire of things she uses over and over again, and does very well.  But you don't see her doing a little bit of everything, like you see on more of the cake shows.  That said, I think what she does is very effective, so I want to learn to emulate some of those signature moves.


Margaret does these royal icing pearls.  Well, my royal icing was too stiff to make mine look like hers, so I settled for old-fashioned dots.  Since my icing was stiff, I had to push down the little points with my fingertip.

Here I'm piping the strings.  You see that you hold the tip away from the cake and let gravity form the string.  You control the pressure and duration to control the length of the string, and you attach it on the other side.   You can also see one of the marred areas of fondant in this picture.

Finishing the string.

The completed cake-- pre-painting.

Everything on the cake was piped with royal icing using various sizes of round tips.  The only exception is the bottom border, which was made from white fondant, twisted into a rope (also an idea from Braun's book).

To finish the cake, I took another page out of Braun's book (so to speak) and hand painted all the piping with a pearl paint, which is made from pearl dust and vodka.  


Fortunately, the pearl color on white is pretty forgiving if you miss a little spot.  A lot of the detailing in Braun's work is painted gold-- that's a lot more obvious.  I'll get there, but I need to find a good gold dust first.

The completed cake.

I think I succeeded in creating a cake with a Margaret Braun flavor, that still has my own personal interpretation.  Obviously with practice, all the techniques will get cleaner and more consistent.  And, ultimately, I'll get my fondant to behave.  I just bought a 2 ft length of PVC pipe that will serve as my new rolling pin....

 

 


It'd make a nice wedding cake top, don't you think?  :)

That's all for now, more royal icing and flowers after my class on Tuesday.

The Cake That Started It All





OK-- this wasn't the first cake that I'd EVER made, but it was the first one I took seriously.  It was made for my friend Stephanie, an office-mate who was moving.  

The idea for this cake was an amalgamation of a chocolate cake I've ogled at my local grocery store and the cream puff cake that Buddy makes in honor of his late father on Cake Boss: Episode 2

I could not find a picture of the cream puff cake, but it is a large cake featuring cream puffs and chocolate covered strawberries, along with classic buttercream borders and a chocolate drizzle.  I decided to incorporate the chocolate covered strawberries and the chocolate drizzle, though I didn't use quite the same approach, since this was only an 8" cake.




The chocolate triangles are a fairly common gimmick on grocery store chocolate cakes, but I think they're really effective!  I didn't want to hand make these triangles, so I carefully cut some Ghirardelli 72% cacao squares along the diagonal to create a similar effect.




The great news about this cake: box chocolate cake mix, and white icing out of a can (I know, gasp).  BUT, for this cake I made a chocolate ganache to fill between the layers.  Ganache is like chocolate truffle filling-- recipes are everywhere.  Basically, you bring some heavy cream to a simmer and pour it over some semi-sweet chocolate chips in a mixing bowl.  Then you stir till all the chocolate is melted.  I added a splash of Kahlua for extra deliciousness.  I also layered some fresh strawberries on top of the ganache when I filled the cake.

I set aside some ganache and put it in a squeeze bottle (a small plastic bottle which can be found by the candy making supplies at your local Michael's or similar).  This is what I used to do the drizzles and the design on the top.

Also, this cake was made before I had invested in any real cake decorating supplies.  All the piping was done using a Farberware pastry bag set I found at the grocery store.

Here is the cake as I served it, surrounded by chocolate covered strawberries:

It was tasty.

So the only supplies I had to buy for this cake (aside from the ingredients):
  • A package of 12" cake rounds
  • A cake caddy to bring it to work-- note that the 12" rounds fit perfectly in the caddy and prevents sliding...
  • A cheap pastry bag and tip set from the grocery store
  • A plastic squeeze bottle for the chocolate
I already had a decent icing spatula on hand. :)

Skills used:
  • Filling the cake: Ok, here was one mini-disaster.  The first step was to pipe some white icing around the circumference (yes, I'm an engineer) of the bottom layer of the cake to create a dam for the filling.  (Note: do this AFTER you put the cake on its cake round).  I did my best to create a sturdy dam, but I was impatient and overzealous when I poured on the ganache.  I made kind of a lot and didn't let it cool as long as I might have (it thickens significantly as it cools), and slowly poured it in the center, using as much as I could.  Well, for a while the surface tension held it, but there was clearly a low spot on my dam.  As I sprinkled on the strawberries, I could see the impending doom.  Soon I found myself trying to hold back the onslaught of ganache as the dam slowly gave under the pressure.  Ultimately, I affixed 2 index cards to the side of the cake (stuck em right on, into the ganache) and put the whole thing in the fridge to set.  The next morning, I took off the index cards and the mistake was easily hidden.  Moral of the story: patience and moderation.
  • Icing the cake:  I made this cake before I even owned a turntable.  This was a bit of a challenge.  Remember the key is to apply a crumb coat (an initial thin layer of buttercream on the outside of the cake in which all the cake crumbs are caught).  You can let the crumb coat set in the open air or in the fridge.  Once it has crusted, apply 1-2 more layers as needed and you won't see any crumbs in your final product (even on a chocolate cake with white icing).  Also, your crumb coat doesn't have to be perfectly smooth-- you can be anal retentive on the final frosting layer... I know I am. :)  This cake was smoothed just using my offset icing spatula.  For round cakes especially, this is easiest if you have a turntable.  I can do a more detailed post on ways to ice a smooth cake in the future.
  • Basic Piping:  Just what you see on the cake.  Mostly some fun work with a relatively large star tip. 
  • Chocolate 'piping': Done with the squeeze bottle.  The drips were done using gravity.  Basically you squeeze a dot on the top rim for 1-3 seconds depending on how long you want the drip to go-- I was going for random lengths so I varied the time.  Then, just let the drip run down the side of the cake.  Smooth frosting is key or the drop can bounce around a little.  Also, make sure you leave enough space between the drips or they can run together (I had that happen once).
