Essence added to patient gourmet's last dish (9)
I believe the answer is:
cassoulet
'dish' is the definition.
(I've seen this before)
'essence added to patient gourmet's last' is the wordplay.
I cannot quite see how this works, but
'essence' could be 'soul' (I've seen this in another clue) and 'soul' is found in the answer.
'patient' could be 'case' (synonyms) and 'case' is found in the leftover letters.
'last' could be 't' (I've seen this in other clues) and 't' is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for cassoulet that I've seen before include "dish" , "French stew made with meat and beans" .)
