Use Dental Floss to Cut Frustrating Cheeses
If you're spreading or mixing the cheese, this obviously isn't necessary, but if you need it cut into nice slices,
If the cheese is small, you can hold it in one hand while your other pulls the floss taught and does the cutting. For larger situations, place cheese on a surface, shimmy the floss beneath it, and simply slice up, holding both ends of the floss and crossing the two ends to complete the cut. Then repeat in equal intervals.
Just don't use the mint-flavored kind. Eww.
