Stewed meat in a thick white sauce (9)
I believe the answer is:
fricassee
'stewed meat in a thick white sauce' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for fricassee that I've seen before include "Stew of meat in thick white sauce" , "eat this?" , "Dish of fried meat in thick sauce" , "Stewed chicken or veal with vegetables in a white sauce" , "food" .)
