Rumbling initially in stomach anticipating rice cooked in spice (8)
I believe the answer is:
turmeric
'spice' is the definition.
(thesaurus)
'rumbling initially in stomach anticipating rice cooked' is the wordplay.
'initially' says to take the initial letters.
'in' means one lot of letters goes inside another.
'stomach' becomes 'tum' ('tum' can be a synonym of 'stomach'**).
'anticipating' is a charade indicator (letters next to each other).
'cooked' indicates an anagram.
The initial letter of 'rumbling' is 'r'.
'r' inserted within 'tum' is 'turm'.
'rice' anagrammed gives 'eric'.
'turm'+'eric'='TURMERIC'
'in' is the link.
(Other definitions for turmeric that I've seen before include "It's hot" , "Bright yellow flavouring" , "Bright yellow spice" , "Yellow aromatic powder used in cooking" , "kitchen ingredient" .)
