Make green tea that's going to pot (8)
I believe the answer is:
generate
'make' is the definition.
(I know this)
'green tea that's going to pot' is the wordplay.
'that's going to pot' indicates anagramming the letters.
'green'+'tea'='greentea'
'greentea' anagrammed gives 'GENERATE'.
(Other definitions for generate that I've seen before include "Give rise to" , "Father" , "Create (power)" , "24 across (anag)" , "Cause to arise; produce" .)
