Gas around warmer white liquid (6,5)
I believe the answer is:
single cream
'warmer white liquid' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'gas around' is the wordplay.
I cannot quite see how this works, but
'gas' could be 'n' (chemical symbol for nitrogen) and 'n' is present in the answer.
'around' could be 're' (regarding) and 're' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for single cream that I've seen before include "emerges from the dairy" , "Dairy product; cleans grime (anagram)" , "food" .)
