Stewed lamb's tail brought up (7)
I believe the answer is:
braised
'stewed' is the definition.
(I've seen this before)
'lamb's tail brought up' is the wordplay.
'tail' suggests the final letters.
'brought up' becomes 'raised' ('raise' can be a synonym of 'bring up').
The last letter of 'lamb' is 'b'.
'b'+'raised'='BRAISED'
(Other definitions for braised that I've seen before include "Stewed in closed pot" , "Fried then slowly stewed" .)
