German or Chinese food, mostly hot (9)
I believe the answer is:
friedrich
'german' is the definition.
(I've seen this before)
'mostly hot' is the wordplay.
'mostly' becomes 'friedric' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'hot' becomes 'h' (abbreviation eg on taps).
'friedric'+'h'='FRIEDRICH'
'or chinese food' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for friedrich that I've seen before include "artist" , "German man" .)
