Right to include one so turmeric-headed dish (7)
I believe the answer is:
risotto
'dish' is the definition.
(I know that risotto is a type of dish)
'right to include one so turmeric-headed' is the wordplay.
'right' becomes 'r' (common abbreviation).
'include' means one lot of letters goes inside another.
'one' becomes 'I' (Roman numeral).
'turmeric-headed' becomes 't' (this might be a standard abbreviation I've not previously seen).
'r'+'to'='rto'
'i'+'so'+'t'='isot'
'rto' enclosing 'isot' is 'RISOTTO'.
Can you help me to learn more?
(Other definitions for risotto that I've seen before include "food dish" , "You cook it in stock" , "scoff" , "F" , "Italian recipe" .)
