Digested as milk may be (9)
I believe the answer is:
condensed
This might be a double definition.
'digested' is the first definition.
(thesaurus)
'milk may be' is the second definition.
'condensed' can be an answer for 'milk' (thesaurus). I am not certain of the 'may be' bit.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for condensed that I've seen before include "Abridged" , "Changed from gas to liquid" , "cut down to size?" , "being thicker" .)
