Months ago, we had an ant problem. Thousands of teeny-tiny yellowish ants crawled around our apartment. (I don't think that we're particularly dirty, but with 2 kids the floor is often covered in crumbs right after vacuuming.) Eventually they made it to the pantry. Oh the horror! It was awful. I had to throw away many boxes of cereal. We had someone come spray but they must of missed a spot, by the pantry no less. So, I took matters into my own hands. I picked up several cans of Raid and proceded to empty the pantry:
Yes, my kitchen is the size of a closet. Seriously. Anyway, I got fancy plastic cereal containers, as well as one for each of the sugars. I filled up the granulated sugar container and had about half a bag that didn't fit. So I stuck it in the freezer with the flour. Bad idea:
These are the shards of sugar that have formed. Sugar to shard ratio is about 1:3. Apparently what works well for flour, does not work for sugar.
Do not store your sugar in the freezer. (though I would guess that most of you are smart enough to have figured that out already)
