Plans to produce starch (6)
I believe the answer is:
charts
'plans' is the definition.
(charting is a kind of planning)
'produce starch' is the wordplay.
'produce' indicates an anagram (I've seen 'producing' mean this).
'starch' anagrammed gives 'CHARTS'.
'to' acts as a link.
(Other definitions for charts that I've seen before include "Maps for ship's captain" , "Starch (anag)" , "Maps; plans" , "Blueprints" , "Maps to aid navigation" .)
