I found this recipe in the Low-Fat cookbook published by Cook's Illustrated. I used, as was recommended by the cookbook, Cabot brand 50% cheddar. The cheese looked pretty white, but the final recipe had a yellow tinge. This cheese is sold in block form. Block low-fat cheese generally melt better than pre-shredded low-fat cheese.
