Dental Floss in the Kitchen
Dental floss is not only for cleaning between your teeth - it also is a handy kitchen tool!
When a recipe calls for splitting a cake into two or more layers horizontally, toothpicks and dental floss make this task easy. Use several toothpicks placed at the proper level (use a ruler if you want precision sized layers) around the outer circumference of the cake, and then use a two-foot piece of waxed or unwaxed dental floss to make a clean straight cut. Just be certain that it is the unflavored type or your cake will have a hint of mint (which you might enjoy!).
Cut pastries in even slices with floss. Floss works well on cinnamon roll dough
Use dental floss to slice crumbly cheeses such as goat cheese or bleu cheese
Use floss to cut a cookie log into individual cookies.
Dental floss can sub in the kitchen for twine when tying herbs and veggies.
No – Do not use in oven.
