Mayall's daddy coming round for spice (7)

I believe the answer is:
paprika
'spice' is the definition.
(I've seen this in another clue)
'mayall's daddy coming round' is the wordplay.
'mayall' becomes 'rik' (I can't justify this - if you can you should believe this answer much more).
'daddy' becomes 'papa' (synonyms).
'coming round' indicates putting letters inside.
'rik' placed inside 'papa' is 'PAPRIKA'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for paprika that I've seen before include "Hot powder" , "strong-tasting spice" , "Irk papa with mild red pepper" , "Orange-red spice" , "Deep red spice" .)
