Tea cooked in space is consumed (5)
I believe the answer is:
eaten
'is consumed' is the definition.
('eaten' can be similar in meaning to 'consumed')
'tea cooked in space' is the wordplay.
'cooked' indicates an anagram.
'in' is an insertion indicator.
'space' becomes 'en'.
'tea' with letters rearranged gives 'ate'.
'ate' inserted within 'en' is 'EATEN'.
(Other definitions for eaten that I've seen before include "Put away" , "used for food" , "dinners should be" , "Taken into the body as food" , "Polished off" .)
