Hard Sugar Remedy?
If brown sugar gets hard you can put a piece of apple in with it to soften it, but what can you do to soften hard white sugar? I have a 4-lb bag that is like a brick---does not respond even to banging on edge of counter--- and the way sugar prices are now I am not inclined to toss it. Suggestions?
There's no reason to throw it out - worse comes to worst you can break it up with a hammer or something and weigh it, or use it when measurements needn't be precise.
But instead of hitting the bag against the edge of the counter, try slamming it down on the long, wide face of the bag. Unless it was exposed to moisture or really extreme humidity, it should eventually loosen up. (You might want to put it in a heavy plastic bag before you really start beating on it, so it doesn't end up all over the place.) I had stocked up on sugar on sale at one point so I've been dealing with this issue a lot lately myself. ;)
The other remedy for hard brown sugar is to put a piece of bread in with it. I'd try that with the white sugar before resorting to the jack hammer.
Or, you could go all Colonial and scrape a knife blade down the side to carve off loose sugar. Probably takes a while.
