Crone is eating good Scots food (6)
I believe the answer is:
haggis
'scots food' is the definition.
'haggis' can be an answer for 'food' (haggis is a kind of food). I'm not certain of the 'scots' bit.
'crone is eating good' is the wordplay.
'crone' becomes 'hag' (synonyms).
'eating' indicates putting letters inside.
'good' becomes 'g' (abbreviation).
'hag'+'is'='hagis'
'hagis' enclosing 'g' is 'HAGGIS'.
Can you help me to learn more?
(Other definitions for haggis that I've seen before include "Scottish grub" , "Burns Night fare" , "Burns' night dish" , "Robert Burns' "Great chieftain o' the puddin'-race"" , "Dish boiled in a skin made from an animal's stomach" .)
