I'm a little stuck... Click here to teach me more about this clue!

'anaesthetise' is the definition.
(freezing is a kind of anaesthetizing)

I don't understand the rest of the clue.

(Other definitions for freeze that I've seen before include "shivering" , "Change to ice" , "Stand motionless" , "Harden into ice" , "Peg" .)

I've seen this clue in the Evening Standard.
