Pasty and wine picked up for ramble (6)
I believe the answer is:
wander
'for ramble' is the definition.
(synonyms)
'pasty and wine picked up' is the wordplay.
'pasty' becomes 'wan' (synonyms).
'and' says to put letters next to each other.
'wine' becomes 'red wine' (red is a type of wine).
'picked up' says the letters should be written in reverse.
'red' backwards is 'der'.
'wan'+'der'='WANDER'
(Other definitions for wander that I've seen before include "Warden (anag.)" , "Go astray" , "go wrong" , "Roam about or digress" , "Leisurely walk" .)
