If you've never tried Butterkase cheese now's the time. It's a very mild, creamy cheese. This sauce is very creamy. I took it up another notch though by adding some shredded White Vermont Cheddar on top before putting under the broiler. Butterkase can be found in most cheese cases at your local grocery store. Boar's Head makes a wonderful Butterkase and you can purchase it at the deli counter or the cheese case. The same with the White Vermont Cheddar
