Puzzle created by savage tucking into lager for example (8)
I believe the answer is:
bewilder
'puzzle' is the definition.
(I know that amaze can be written as bewilder)
'savage tucking into lager for example' is the wordplay.
'savage' becomes 'wild' (similar in meaning).
'tucking into' is an insertion indicator.
'lager for example' becomes 'beer' (lager is a kind of beer).
'wild' put inside 'beer' is 'BEWILDER'.
'created by' acts as a link.
(Other definitions for bewilder that I've seen before include "Flummox, confuse" , "Confuse - perplex" , "Confuse totally" , "Perplex the wild beer" , "fox" .)
