Witches getting round a soldier for some pudding (6)
I believe the answer is:
haggis
'some pudding' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'witches getting round a soldier' is the wordplay.
'witches' becomes 'hags' ('hag' can be a synonym of 'witch').
'getting round' indicates putting letters inside.
'a soldier' becomes 'GI' (GI can mean a US soldier).
'hags' going around 'gi' is 'HAGGIS'.
'for' is the link.
Can you help me to learn more?
(Other definitions for haggis that I've seen before include "boil-in-bag meal" , "Scottish dish boiled in sheep's stomach" , "Robert Burns' "Great chieftain o' the puddin'-race"" , "Dish boiled in a skin made from an animal's stomach" , "Hi gags about traditional Scottish dish" .)
