Bit of rice put in to achieve texture (5)
I believe the answer is:
grain
'texture' is the definition.
(grain is a kind of texture)
'bit of rice put in' is the wordplay.
'bit of' indicates taking the first letters.
'put' becomes 'gain' (I can't explain this - if you can you should believe this answer much more).
'in' indicates putting letters inside.
The first letter of 'rice' is 'r'.
'r' placed into 'gain' is 'GRAIN'.
'to achieve' acts as a link.
Can you help me to learn more?
(Other definitions for grain that I've seen before include "Small hard particle of anything" , "Tiny amount" , "little salty bit" , "Silo contents" , "Pattern of lines in wood" .)
