Macho aggression upset Mike, chap that's often eaten at curry-house (8)
I believe the answer is:
turmeric
'macho aggression upset' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'mike chap that's often eaten at curry-house' is the wordplay.
I cannot quite see how this works, but
'mike' could be 'm' (phonetic alphabet: alpha, bravo, charlie etc.) and 'm' is located in the answer.
'chap' could be 'eric' and 'eric' is located in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for turmeric that I've seen before include "A curry spice; cruet rim (anag.)" , "It's hot" , "Yellow spice used in curry" , "Powdered plant stem used as condiment" , "kitchen ingredient" .)
