Makes twenty-four 2-inch brownies

For the chewiest texture, it is important to let the brownies cool thoroughly before cutting. If your baking dish is glass, cool the brownies 10 minutes, then remove them promptly from the pan (otherwise, the superior heat retention of glass can lead to overbaking). While any high-quality chocolate can be used in this recipe, our preferred brands of bittersweet chocolate are Callebaut Intense Dark Chocolate L-60-40NV and Ghirardelli Bittersweet Chocolate Baking Bar. Our preferred brand of unsweetened chocolate is Scharffen Berger. Leftovers can be stored in an airtight container at room temperature for up to 4 days.
