Woman holds infant fed with a Mexican dish (9)
I believe the answer is:
enchilada
'mexican dish' is the definition.
(enchilada is a type of Mexican dish)
'woman holds infant fed with a' is the wordplay.
'woman' becomes 'ena' (woman's name).
'holds' means one lot of letters goes inside another.
'infant' becomes 'child' (I've seen this before).
'fed with' is an insertion indicator.
'child' going around 'a' is 'chilad'.
'ena' enclosing 'chilad' is 'ENCHILADA'.
(Other definitions for enchilada that I've seen before include "Tortilla and chilli dish" , "Filled tortilla served with chilli sauce" , "hot dish" , "Rolled stuffed tortilla with chilli sauce" , "spicy titbit" .)
