Variety of steak is black in hue (1-4)
I believe the answer is:
t-bone
'variety of steak' is the definition.
't bone' can be an answer for 'steak' (I've seen this before). I'm not certain of the 'variety of' bit.
'black in hue' is the wordplay.
'black' becomes 'b' (abbreviation as in pencil classifications).
'in' means one lot of letters goes inside another.
'hue' becomes 'tone' (tone can mean a colour or shade).
'b' placed within 'tone' is 'T-BONE'.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for t-bone that I've seen before include "Large cut of steak" , "Kind of steak" , "Cut of beef" , "Choice cut of steak" , "Choice piece of loin steak" .)
