I was watching Steven & Chris on CBC today and Christina Marsigliese (www.christinamarsigliese.com) was on the show making these brownies. They look absolutely delicious, chewy, fudgy, and best of all for a gluten free recipe they use ingredients anyone would have in their pantry. I learned something new about chocolate while watching this episode as well. This recipe calls for bittersweet chocolate (70% cocoa solids), you can sub semisweet (54% cocoa solids), but should not go to an unsweetened chocolate. The chemistry of the recipe is dependant on the amount of cocoa butter in the chocolate, if you sub a chocolate with a much higher percentage of cocoa solids your recipe may not turn out. Make sure not to overbake these brownies. A toothpick inserted in the middle of the brownies should come out with some moist crumbs stuck to it. I have not made these yet, but do intend to try them myself.
