I have juice all the time, but I pile my roasting pan quite high and then have to stir
it up several times. I use less oil, some water but I also keep the pan covered with a piece of foil for the first 45 minutes or so, then uncover it for the rest of the roasting. It just dawned on me that I forgot the cheese last night---I must remedy that tonight! I added some rosemary to the pan last night, but I'm not liking it so much. I also add a generous splash around of balsamic sometimes.
