[i] I've been seeing this Mirror Icing on several cakes and I'm wondering what this is. Can anyone tell me about it? Do you have to buy it or is a recipie for it? Thanks for any info!
Can you post a pic so we know what you're talking about. this sounds interesting. Thanks.
Why isn't that ganache with a bit of corn syrup added?
Ganache with corn syrup doesn't maintain the shine that you get with a well made mirror glaze.
There is a recipe for it in Rose's Heavenly Cakes. . . there are also recipes on the 'net if you Google Chocolate Mirror Glaze.
I've made it once http://grandmasugarskitchen.blogspot.ca/2012/03/two-cakes-today.html
The cake (ganache/mousse) under the glaze must be perfectly smooth. The slightest flaw will show (as you can see along the edge of my own example), though once it dries, I suppose you could give it a second coat to disguise the flaws.
