Culinary skill shown by family filling container (6)
I believe the answer is:
baking
'culinary skill' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'family filling container' is the wordplay.
'family' becomes 'kin' (synonyms).
'filling' indicates putting letters inside.
'container' becomes 'bag' (bag is a kind of container).
'kin' put within 'bag' is 'BAKING'.
'shown by' acts as a link.
Can you help me to learn more?
(Other definitions for baking that I've seen before include "Making bread, cakes etc" , "Making bread, cake or pastry" , "Very hot; making bread" , "Cooking by dry heat" , "Making bread, cake, etc." .)
