Standard part of a risotto recipe (5)
I believe the answer is:
stock
This clue could be a double definition.
'standard' is the first definition.
(synonyms)
'part of a risotto recipe' is the second definition.
'stock' can be an answer for 'part' (stock is a kind of part). I'm not certain of the 'of a risotto recipe' bit.
Can you help me to learn more?
(Other definitions for stock that I've seen before include "Neck adornment" , "Wares" , "Merchandise - ancestry" , "Supply; part of rifle" , "Neck garment" .)
