How can they even consider it liquid? Makes no sense.
The TSA restriction is not just against liquids. Other countries / securities likely have similar wording.
The wording on the TSA website is:
"liquid, aerosol, gel, cream or paste"
Chumus would be considered a cream or paste.
I had a larger then 3oz deodorant (aerosol) taken away going through security in Asia (TPE IIRC).
