Has anyone figured out away of keeping your spices ie. salt, onion powder, garlic powder from becoming a clump of spices in the jar? I've tried the rice in the salt container with no real results.
At home I keep them in the freezer. Started doing this during our ten years in the Caribbean, where spices lose taste a few months after opening.
But our RV freezer is the size of a shoebox, so I just bring them along in the tiny spice rack above the tiny sink on our long trips and hope they hang in there.
