It warms bishop, gaunt, esurient, drained (7)

I believe the answer is:

blanket

I'm a little stuck... Click here to teach me more about this clue!

'it warms' is the definition.
The definition suggests a singular noun which matches the answer.

'bishop gaunt esurient drained' is the wordplay.
'bishop' becomes 'B' (chess abbreviation).
'gaunt' becomes 'lank' (I've seen this before).
'drained' means to remove the middle letters.
'esurient' with its middle taken out is 'et'.
'b'+'lank'+'et'='BLANKET'

Can you help me to learn more?

(Other definitions for blanket that I've seen before include "Warm covering" , "Cover with a thick layer" , "See 12" , "Bed cover; inclusive" , "Woollen bed cover" .)

I've seen this clue in The Telegraph.
