I live in Los Angeles, where it's not typically humid. But I've grown tired of having onion powder clump into a rock-hard block. My current supply is in its original bottle; I went to the trouble of chiseling out and grinding the whole thing back to powder, and tried various "remedies": dried beans, grains of rice, keeping it in the freezer, putting a silica gel packet in the bottle, and BOTH the packet AND lots of rice grains.
Nothing worked. Still clumped up and starting to get hard again.
So, is there REALLY a remedy for clumping that truly works? Or should I give up trying to find this holy grail, or just give up on onion powder?
