I want to make pizza today for a dinner, making the dough from scratch. I have see several recipes for the dough and how to make it using a stand mixer but there is a vague ingredient in the recipe "let rise". My apartment is does not have central heating so the temperature varies greatly from place to place. If I am making a pound of dough and room temperature is 60 degrees, for example, how long will it take to rise? how much of a difference if it is 55 degrees?
