In general, an assortment of cruets (6)
I believe the answer is:
custer
'in general' is the definition.
'custer' can be an answer for 'general' (I've seen this before). I am unsure of the 'in' bit.
'an assortment of cruets' is the wordplay.
'an assortment of' indicates anagramming the letters (I've seen this in other clues).
'cruets' anagrammed gives 'CUSTER'.
Can you help me to learn more?
(Other definitions for custer that I've seen before include "Little Bighorn loser" , "US general killed by Indians in eighteen-seventy-six" , "US cavalry leader" , "General who died at battle of Little Bighorn" , "General who was killed at the battle of Little Bighorn" .)
