I am new here and this is my first post. I hope I am placing it in the correct forum. I am new to cookie decorating, having only made my second batch of cookies. I am still in the process of decorating them. The first batch of cookies I made were delicious, but some of them spread a little. As a result, I did not decorate those that spread. I made the second batch using less flour but adding cornstarch. They did not spread and they tasted good, but are not as delicious as the first batch. Someone told me that if I would add a pinch of cream of tartar to my first recipe that did not have cornstarch, then they would not spread. Is that true that a pinch of cream of tartar keeps cookies from spreading? I really want to stick with my first recipe, but I don't want them spreading either.
