Crossword Genius

To begin with, mince tarts! (5)

Ross

I believe the answer is:

start

'to begin' is the definition.
('start' can be a synonym of 'begin')

'mince tarts' is the wordplay.
'mince' indicates an anagram.
'tarts' anagrammed gives 'START'.

'with' is the link.

(Other definitions for start that I've seen before include "Outset" , "Origin" , "Opening - jump" , "Begin to recoil?" , "Commencement" .)

I've seen this clue in the Evening Standard.
