Grasps biscuits I've put out (7)
I believe the answer is:
digests
'grasps' is the definition.
(digesting is a kind of grasping)
'biscuits i've put out' is the wordplay.
'biscuits' becomes 'digestives' (I've seen this before).
'put out' indicates named letters should be taken away.
'digestives' with 'ive' taken out is 'DIGESTS'.
(Other definitions for digests that I've seen before include "summaries" , "Thoroughly absorbs" , "Breaks down food" , "condensation?" .)
