More reckless son provides the bacon (7)
I believe the answer is:
rashers
'the bacon' is the definition.
'more reckless son' is the wordplay.
'more reckless' becomes 'rasher' ('rash' can be a synonym of 'reckless').
'son' becomes 's'.
'rasher'+'s'='RASHERS'
'provides' is the link.
(Other definitions for rashers that I've seen before include "eaten at breakfast" , "Tasty strips of bacon" , "Meat slices" , "Thin slices of bacon" .)
