Flourish this grain husk meal (8)
I believe the answer is:
brandish
'flourish' is the definition.
(I know that flourish can be written as brandish)
'grain husk meal' is the wordplay.
'grain husk' becomes 'bran' (I've seen this in another clue).
'meal' becomes 'dish' (a dish is a particular meal).
'bran'+'dish'='BRANDISH'
'this' is the link.
(Other definitions for brandish that I've seen before include "Flourish, wield" , "Wave something about threateningly" , "Display" , "Wave vigorously" , "Flourish aggressively" .)
