Tool to gently boil Thai rice, primarily to be eaten (8)
I believe the answer is:
strimmer
'tool' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'gently boil thai rice primarily to be eaten' is the wordplay.
'gently boil' becomes 'simmer' (I've seen this before).
'primarily' suggests taking the first letters.
'to be eaten' indicates putting letters inside.
The first letters of 'thai rice' is 'tr'.
'simmer' going around 'tr' is 'STRIMMER'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for strimmer that I've seen before include "Garden equipment" , "Gardening implement" , "Cutter for rough grass etc" , "Machine for cutting grass edges" , "Hand-held grass cutter" .)
