Onion Powder always hardens to cement in my pantry!
It's true I rarely use it, it's only there for the occasional spice blend recipe. I know it's not fresh; I'm sure it's the "new jar" I got when we remodeled the kitchen 5 years ago! But the garlic powder is fine, why does the onion powder become a rock? I'd be willing to buy a new jar if someone could tell me how to keep it soft enough to measure.
