While a kitchen scale is not necessary to making this recipe, I highly recommend getting one. I like this scale. Weighing the ingredients guarantees accuracy and will result in rolls that look just like mine. Everyone measures flour a little differently, and you might end up with too much or too little if you use measuring cups. Plus, I love to weigh the dough and do a little math to make sure that I split the dough into 25 equal pieces. That way all of my rolls are exactly the same size and all cook perfectly.
