Sweet stuff from bee, say, covering rough gem (4,6)
I believe the answer is:
stem ginger
'sweet stuff' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'bee say covering rough gem' is the wordplay.
'bee say' becomes 'stinger' (I can't explain this - if you can you should give a lot more credence to this answer).
'covering' is an insertion indicator.
'rough' indicates anagramming the letters (a rough or broken ordering of the letters).
'gem' is an anagram of 'emg'.
'stinger' placed around 'emg' is 'STEM GINGER'.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for stem ginger that I've seen before include "sort of ice cream" , "spicy ingredient" , "Crystallised root" , "As food" , "Merging set (anag.)" .)
