Frog recipe - nothing to do without (5)
I believe the answer is:
forgo
'do without' is the definition.
(I've seen this in another clue)
'frog recipe nothing' is the wordplay.
'recipe' is an anagram indicator.
'nothing' becomes 'O' (looks like zero - 0).
'frog' anagrammed gives 'forg'.
'forg'+'o'='FORGO'
'to' is the link.
(Other definitions for forgo that I've seen before include "pass up" , "Abjure" , "Go without (something)" , "Waive" , "Do without (something desirable)" .)
