Saw baked dish in European shop display in the beginning (6)
I believe the answer is:
espied
'saw baked dish' is the definition.
'espied' can be an answer for 'saw' (I've seen this before). I'm not certain of the 'baked dish' bit.
'in european shop display in the beginning' is the wordplay.
'in' indicates putting letters inside.
'european' becomes 'E' (abbreviation e.g. EU).
'shop display' becomes 'sped' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'the beginning' says to take the initial letters (I've seen 'the beginning of' mean this).
The first letter of 'in' is 'i'.
'e'+'sped'='esped'
'esped' enclosing 'i' is 'ESPIED'.
Can you help me to learn more?
(Other definitions for espied that I've seen before include "Caught sight of (archaic)" , "Saw (archaic)" , "Glimpsed" , "Spotted; saw" , "Caught sight of (poetic)" .)
