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 am unsure of the 'variety of' bit.
'black in hue' is the wordplay.
'black' becomes 'b' (abbreviation as in pencil classifications).
'in' is an insertion indicator.
'hue' becomes 'tone' (tone can mean a colour or shade).
'b' inserted into 'tone' is 'T-BONE'.
'is' is the 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" .)
