Things You'll Need
Parmesan cheese undergoes an extensive aging process to develop its rare flavor described as being akin to savory. The Japanese call Parmesan cheese's flavor "umami," but as Parmesan cheese sits in storage in a refrigerator, it dries out and this sought-after umami taste deteriorates after a month. Softening your dried out Parmesan cheese can make it easier to grate and taste better. As with the making of the cheese itself, softening dried out Parmesan cheese will take time. Plan at least one day before you need your cheese to use this remedy.
