From Australian Super Food Ideas. A very tasty potato dish. Have included cooking time for boiling potatoes and making sauce and oven time. I think you could make this ahead and keep in the refrigerator but would have to take out for at least 30 minutes before cooking and would cook at a slightly lower temperature for longer to ensure it heats all the way through. NOTE 28 May'10 - Tasty cheese = cheddar, usually a young one; my personal preference is a sharp or aged vintage one depending what I have on hand but all will work well but just give a different depth of flavour. Also a sprinkle of paprika on top (or mixed with breadcrumbs does not go wrong - not unusual for me to do on a cheesy topped dish).
