Keep or throw the confectioner’s sugar?

Save or discard the powdered sugar?

Last weekend, I reluctantly tackled my annual pantry clean-out. I came across some expired cans of baked beans, various condiments, and a few mouse droppings. Thankfully, they seemed to be mostly around the dog food, which means those little critters were just enjoying the stray kibble and didn’t get into the plastic storage container.

Upon closer inspection, I discovered that the mice had nibbled on two bags of confectioner’s sugar. Should I really toss it? My frugal side is hesitant, but my better judgment says it’s time to let it go.
