Dish he loathed, not surprisingly, touring India (4-2-3-4)
I believe the answer is:
toad-in-the-hole
'dish' is the definition.
(sausage and batter dish)
'he loathed not surprisingly touring india' is the wordplay.
'surprisingly' is an anagram indicator (a surprising ordering of the letters).
'touring' means one lot of letters goes inside another (tour can mean to go around).
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'he'+'loathed'+'not'='heloathednot'
'heloathednot' anagrammed gives 'toadnthehole'.
'toadnthehole' enclosing 'i' is 'TOAD-IN-THE-HOLE'.
(Other definitions for toad-in-the-hole that I've seen before include "Battered sausage" , "Sausage and batter dish" , "Bangers and batter" , "Batter pudding containing sausages" , "Sausages baked in batter" .)
