Scraps -- skin of sausages left in fresh suet (7)
I believe the answer is:
tussles
'scraps' is the definition.
(I know this)
'skin of sausages left in fresh suet' is the wordplay.
'skin of' means to remove the middle letters.
'left' becomes 'l' (common abbreviation).
'in' indicates putting letters inside.
'fresh' indicates anagramming the letters (a fresh re-ordering of the letters).
'sausages' with its centre removed is 'ss'.
'ss'+'l'='ssl'
'suet' is an anagram of 'tues'.
'ssl' placed inside 'tues' is 'TUSSLES'.
(Other definitions for tussles that I've seen before include "Struggles" , "Scraps" , "Scuffles, dogfights" .)
