Fool in the morning making the tea (5)
I believe the answer is:
assam
'the tea' is the definition.
(I've seen this before)
'fool in the morning' is the wordplay.
'fool' becomes 'ass' (ass is a kind of fool).
'in the morning' becomes 'am'.
'ass'+'am'='ASSAM'
'making' acts as a link.
(Other definitions for assam that I've seen before include "I'll provide lots of tea" , "Indian state famous for tea" , "region out east" , "Variety of tea" , "Tea-growing state in north-east India" .)
