Makes sense for a date to cook spud (4,2)
I believe the answer is:
adds up
'makes sense' is the definition.
('add up' can be a synonym of 'make sense')
'a date to cook spud' is the wordplay.
'a date' becomes 'AD' (AD is an example).
'to cook' is an anagram indicator.
'spud' is an anagram of 'dsup'.
'ad'+'dsup'='ADDS UP'
'for' is the link.
(Other definitions for adds up that I've seen before include "Stands to reason" , "Totals" , "Tots" , "Sums - makes sense" , "Puts two and two together" .)
