What could be hot and horrid ashes all over the place (11)
I believe the answer is:
horseradish
'what could be hot' is the definition.
I can't judge whether this defines the answer.
'horrid ashes all over the place' is the wordplay.
'all over the place' indicates an anagram.
'horrid'+'ashes'='horridashes'
'horridashes' is an anagram of 'HORSERADISH'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for horseradish that I've seen before include "Plant with root used for pungent condiment" , "Sauce served with beef" , "Root used in sauce" , "that's hot" , "Source of sauce to go with beef" .)
