No Yeast Option: If you do not have access to yeast or simply cannot use, you can omit the yeast and instead use 1 1/2 teaspoons baking powder and 1 teaspoon baking soda, added with the flour. You can skip the rising and instead just let the dough rest 30 minutes, then roll, rest again another 15-20 minutes, then bake. The rolls will be a little less fluffy, but will be great!
