Bishop goes in for starter of spicy soup (6)
I believe the answer is:
bisque
'soup' is the definition.
(bisque is a kind of soup)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for bisque that I've seen before include "Rich shellfish soup - lobster is nice" , "pot?" , "golf handicap" , "Cream soup made with shellfish" , "Thick shellfish soup" .)
