I have alway had luck using Guittard Choc-Au-Lait chips 3:1 ratio. After blending chips and cream I use my immersion blender to get it really smooth, then I put plastic wrap directly on top and let it sit on the counter overnight or most of the day. If the consistency seems a bit stiff I put it in the microwave for just a few seconds and stir, perfect for covering a cake I do chill the cake for a few hours before covering with fondant. Hope this helps
I actually saw these chips in the store yesterday. I was planning on making sour cream ganache this week. Anyway, those aren't a true white chocolate, but they do have some cocoa butter in them. I'm wondering if this is making the difference in your result.
Don't forget, ladies, that if cocoa butter isn't the first or second ingredient, it's not really white chocolate. has anyone tried a sour cream ganache?
