Best Brands for Cooking with Chocolate
Cooking and baking is all about taste, primarily your taste and the tastes of the people you are cooking for. So if you are really serious about finding the best brands for cooking with chocolate, you should do your own taste tests. It really doesn't matter if a "chocolate expert" says that a given brand is the best in the world. If you don't like it, you don't have to buy it again after trying it out.
It can also be helpful to compare chocolate products that are made by the same company. For example, Hershey's offers its "regular" unsweetened cocoa as well as Hershey's Special Dark Cocoa. You won't know which one is better until you try them out for yourself.
In addition, check out the smaller companies that offer chocolate cooking and baking products. For example, Dagoba offers products such as organic cacao powder and organic unsweetened dark chocolate. Guittard Chocolate has Cocoa Rouge unsweetened cocoa powder that's definitely worth trying.
Go out and explore. There is a whole world of chocolate waiting for you to try out in your kitchen. Only you can really decide the best brands for chocolate to suit your inner chocoholic.
