For me, nothing beats Ghirardelli. Their squares are superior and just the right amount for snacking, and it's the only chocolate I use for chocolate chip cookies. Their 60% cacao chips are amazing (and I will eat a tablespoon while making my recipe, so my cookies are always short a few chips). I think they chose the Ghirardelli chips as superior on America's Test Kitchen. Growing up, I used Toll House (like most people) until I tried the 60% cacao chips and went, "What the heck have I been doing all these years?" Toll House tastes like over sweetened wax blobs next to Ghirardelli.
For cakes, brownies, and other baking, I will also use Guittard, or even Hershey's Dutch process cocoa powder. This reminds me that I need to stock my pantry for holiday baking. I'm making Tiramisu this year and need a really good chocolate and espresso powder for that.
Now I'm off to replace the struts in my SUV hatch. There's nothing I can't do!
Mark!
My experience also.
Im a Ghirardelli fan also!
