It doesn’t matter if you are making holiday cookies or just for a family treat, if the cookie dough sticks to the rolling pin it becomes more of a chore than fun. By  dusting the rolling pin with cornstarch instead of flour you will have a much easier job. This silky powder will absorb the moisture and oils that makes the dough sticky so your rolling pin will glide through the dough. Also, cornstarch is gluten-free so it doesn’t make the dough tough or heavy.
