Spice in mustard regularly smeared amid basmati rice in a stew (8)
I believe the answer is:
turmeric
'spice' is the definition.
(type of spice)
'mustard regularly smeared amid basmati rice in a stew' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'rice' is 'eric' which is within the answer.
The remaining letters 'turm' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'in' acts as a link.
Can you help me to learn more?
(Other definitions for turmeric that I've seen before include "It's hot" , "Powdered plant stem used as condiment" , "ginger relative" , "Bright yellow flavouring" , "Spice with yellowing effect" .)
