Forked out around two pounds for pasty (6)
I believe the answer is:
pallid
'for pasty' is the definition.
(synonyms)
'forked out around two pounds' is the wordplay.
'forked out' becomes 'paid' (to fork out for something is to pay for it).
'around' means one lot of letters goes inside another.
'two' shows that letters should be duplicated.
'pounds' becomes 'l' (abbreviation e.g. Lsd - pounds, shillings, pence).
'l' doubled is 'll'.
'paid' going around 'll' is 'PALLID'.
(Other definitions for pallid that I've seen before include "Pale and wan (6)" , "Anaemic" , "Unhealthily pale" , "Colourless, wan" , "Pale, insipid" .)
