Yeah, that’s right, the tongue. Next you’re going to add in your flour, salt and baking soda. I always leave the chocolate chips out of this phase because I don’t want them to break while the flour gets incorporated. So the best tip here that I can give you is to make sure that you don’t over mix the flour into the batter. This causes the gluten to develop and you’ll have a tough cookie on your hand. No bueno. Instead, focus on mixing the flour until it just barely gets incorporated to where you can’t see the flour any more. This takes about 30 seconds or so. Then, add in the chocolate chip cookies mixing them in for another 15-30 seconds or so, or until they are well mixed in.
