Cook wraps poorly with fancy trimmings (6)
I believe the answer is:
frilly
'fancy trimmings' is the definition.
'frilly' can be an answer for 'fancy' (I've seen this before). I am unsure of the 'trimmings' bit.
'cook wraps poorly' is the wordplay.
'cook' becomes 'fry' (frying is a kind of cooking).
'wraps' is an insertion indicator (inserted letters get wrapped up).
'poorly' becomes 'ill' (synonyms).
'fry' going around 'ill' is 'FRILLY'.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for frilly that I've seen before include "Having flounces, ruffles, etc" , "Fancy" , "ruffled" .)
