Dish in Madrid? Wrong one everyone sent back (8)
I believe the answer is:
tortilla
'dish in madrid?' is the definition.
'tortilla' can be an answer for 'dish' (I have seen 'Mexican dish' mean 'tortilla' so perhaps 'dish' could also mean 'tortilla'). I'm unsure of the 'in madrid?' bit.
'wrong one everyone sent back' is the wordplay.
'wrong' becomes 'tort' (legal term).
'one' becomes 'i' (Roman numeral).
'everyone' becomes 'all' (all people).
'sent back' shows that the letters should be reversed in order.
'all' written backwards gives 'lla'.
'tort'+'i'+'lla'='TORTILLA'
Can you help me to learn more?
(Other definitions for tortilla that I've seen before include "In which one may see salsa" , "Mexican corn meal pancake" , "Mexican 7 across" , "Mexican corn-meal pancake" , "Mexican snack" .)
