Hi Ellen, the weight of each piece of dough depends on how large you want the rolls to be. For large dinner rolls, each piece should weigh about 75 grams. If you want to make smaller, more traditional-sized dinner rolls, each piece should weigh closer to 50 grams. The amount of time they'll take to rise depends on the temperature of your rising environment. Give them about an hour at room temperature to see if they become a bit puffy, but give them extra time if they haven't changed much. Happy baking! Kye@KAF
