Friend given a raise celebrated, making tea (7)
I believe the answer is:
lapsang
'tea' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'friend given a raise celebrated' is the wordplay.
'friend given' becomes 'pal' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'a raise' is a reversal indicator.
'celebrated' becomes 'sang' (singing might be done as part of a celebration).
'pal' reversed gives 'lap'.
'lap'+'sang'='LAPSANG'
'making' is the link.
Can you help me to learn more?
(Other definitions for lapsang that I've seen before include "Variety of Chinese tea with a smoky flavour" , "one of its teas" .)
