I use Washington potatoes but any good russet works well. This has been a great side dish that everyone loves and it is perfect for a potluck. I've always made this in my Cuisinart, no need to wash between steps. The prep time is for using a food processor, but you can do it the old fashioned way too!
Another Swedish recipe that I am posting for ZWT6.
Herrgårdsost is a semi-hard yellow cheese made from cow's milk with a mild nuttiness similar to Gruyere or aged cheddar. It has a few small holes (like Swiss cheese does) and is produced in large wheels coated with yellow wax. The name means "manor house cheese."
