Thick and rich: like the elite? (6)
I believe the answer is:
creamy
'thick' is the definition.
(similar in meaning)
'rich like the elite?' is the wordplay.
I cannot quite see how this works, but
'like' could be 'y' (similar in meaning) and 'y' is present in the answer.
'elite?' could be 'cream' (as in the cream of the crop) and 'cream' is found within the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'and' is the link.
Can you help me to learn more?
(Other definitions for creamy that I've seen before include "Buttery" , "A mercy (anag)" , "Rich like fatty part of milk" , "Rich and smooth like milk product" , "Emulsified" .)
