Rake is broken in pigpen — like some bacon? (7)
I believe the answer is:
streaky
'like some bacon?' is the definition.
(I've seen this before)
'rake is broken in pigpen' is the wordplay.
'is broken' indicates an anagram.
'in' indicates putting letters inside.
'pigpen' becomes 'sty' (synonyms).
'rake' anagrammed gives 'reak'.
'reak' put inside 'sty' is 'STREAKY'.
(Other definitions for streaky that I've seen before include "Having lines of differing colours" , "sort of bacon" , "Type of bacon" , "particular bacon?" , "of uneven quality" .)
