Sweet paintings etc gallery put back in container (5,5)
I believe the answer is:
tarte tatin
'sweet' is the definition.
I know nothing about this answer so I can't tell whether this works.
'paintings etc gallery put back in container' is the wordplay.
'paintings etc' becomes 'art' (works of art).
'gallery' becomes 'tate' (Tate Modern, Tate Britain etc).
'put back' says the letters should be written in reverse.
'in' means one lot of letters goes inside another.
'container' becomes 'tin' (tin is a kind of container).
'tate' in reverse letter order is 'etat'.
'art'+'etat'='artetat'
'artetat' put into 'tin' is 'TARTE TATIN'.
Can you help me to learn more?
(Another definition for tarte tatin that I've seen is " Apple pie".)
