Can someone help me with a rough estimate as to how much chocolate I would need for ganache? I'm making a 2 layer 8 inch cake. I'm planning to cover the cake with a coat first with a 2 to 1 ratio ganache to get a smooth surface and then I'm using the 1 to 1 ratio for the shiny pourable ganache. I'm thinking I'll use the ghiradelli semi sweet bar which I believe is a 4 oz package. TIA!
Depending on how thick or thin you do your ganache layer will affect how much you need to make. I use the Wilton Serving Chart to help figure out how much buttercream I need and use the same for figuring out ganache and IMBC. According to their chart, you need 4 cups to cover and fill 2-8" rounds. From experience, 1 lb (16oz) of chocolate 2:1 ratio yields approximately 3 cups of ganache.
For 4 cups you'll need approximately 1lb 5oz chocolate for the 2:1 ratio.
I haven't done pourable ganache yet so I can't help suggest how much you'll need for that.
Thank you so much! I've bought my chocolate and am ready to go!
