Another great Cook's Illustrated cookie that is truly soft and chewy. Measure the molasses in a liquid measuring cup. If you find that the dough sticks to your palms as you shape the balls, moisten your hands occasionally in a bowl filled with cold water and shake off the excess. Bake the cookies one sheet at a time. If baked two sheets at a time, the cookies started on the bottom rack won’t develop the attractive cracks. The cookies should look slightly raw and under baked when removed from the oven. If you plan to glaze the cookies save the parchment paper used to bake them.
