Gather pear was cooked (4)
I believe the answer is:
reap
'gather' is the definition.
(I know that reap is a kind of gather)
'pear was cooked' is the wordplay.
'was cooked' indicates anagramming the letters.
'pear' with letters rearranged gives 'REAP'.
(Other definitions for reap that I've seen before include "Use a scythe" , "Save harvest, glean" , "''As you sow, so you . . . .'' (4)" , "Get -- derive" , "Cut the corn" .)
