Hippies' dish (3)
I believe the answer is:
pie
'dish' is the definition.
(I've seen this before)
'hippies'' is the wordplay.
'PIE' is hidden within the letters.
But, I am unsure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for pie that I've seen before include "something with custard, say" , "Food baked under pastry" , "Pastry-crust savoury" , "Fruit or meat dish" , "Crusty dish" .)
