Prepare for cooking a plant — do it with mincing? (3,3,4)
I believe the answer is:
top and tail
'prepare for cooking' is the definition.
I know nothing about this answer so I can't tell whether this works.
'a plant do it with mincing?' is the wordplay.
'with mincing?' indicates anagramming the letters (letters get minced or chopped).
'a'+'plant'+'do'+'it'='aplantdoit'
'aplantdoit' with letters rearranged gives 'TOP AND TAIL'.
Can you help me to learn more?
(Other definitions for top and tail that I've seen before include "quickly see to baby" , "cursory wash" , "Scamp washing baby" , "Prepare (vegetables)" .)
