Cook us tea, perhaps (5)
I believe the answer is:
saute
'cook' is the definition.
(I've seen this before)
'us tea perhaps' is the wordplay.
'perhaps' indicates an anagram.
'us'+'tea'='ustea'
'ustea' is an anagram of 'SAUTE'.
(Other definitions for saute that I've seen before include "Cooked in a little hot fat" , "Fried quickly in a little fat" , "fried spuds and the like" , "Cook" , "Fried quickly in small amount of fat" .)
