Baking

I'm making Chex Mix today and pulled out the onion powder only to find that the 20 oz pkg was a solid brick. Somewhere along the line the cap was probably left open and moisture got in. But... I needed onion powder so I used my knife and got as much out of the container as I could then pulled out a mortar & pestle and squished it into submission so I could use it. Then I found the expiration date... Aug '07.  So a grocery store run was in order.
