Start again with a newer blend (5)
I believe the answer is:
renew
'start again' is the definition.
(I've seen this before)
'a newer blend' is the wordplay.
'blend' indicates an anagram (I've seen 'blended' mean this).
'newer' with letters rearranged gives 'RENEW'.
'with' is the link.
(Other definitions for renew that I've seen before include "Update library book, acquaintance, etc" , "Begin again" , "Revive" , "Restore - recommence" , "what regeneration will do" .)
