A suggestion; the hotter the broth is the faster the risotto will get done. Some cooks have it simmering in a pot next to the risotto.
Also,,if you like the idea of dipping bread into the extra liquid just have a little extra left in the finished product. You are better off with a little too much liquid than too little. It helps avoid the rice sticking to the bottom of the pot and having your risotto turn out too sticky.
