Father messed up a pinny when grabbing good item in the kitchen (6,3)
I believe the answer is:
frying pan
'item in the kitchen' is the definition.
(vessel used when cooking)
'father messed up a pinny when grabbing good' is the wordplay.
'father' becomes 'fr' (abbreviation as in a priest's title).
'messed up' indicates anagramming the letters.
'when grabbing' means one lot of letters goes inside another (inserted letters are grabbed).
'good' becomes 'g' (abbreviation).
'a'+'pinny'='apinny'
'apinny' anagrammed gives 'yinpan'.
'yinpan' placed around 'g' is 'yingpan'.
'fr'+'yingpan'='FRYING-PAN'
(Other definitions for frying pan that I've seen before include "Kitchen item" , "Kitchen utensil" , "One found in kitchen" , "Skillet" , "One used to cook breakfast" .)
