If you have an immersion blender, this is a great time to use it and save yourself energy. Finally, the recipe suggests you preheat your oven before you begin. For me, this led to an oven running at 400 degrees for an hour. But some ovens take longer than others to preheat; if yours is one of them, turn it on when the recipe suggests. If not, find a time 20 minutes or so before you need to bake it.
