Cheese principally for epicurean travellers abroad (4)
I believe the answer is:
feta
'cheese' is the definition.
(I know that feta is a type of goat cheese)
'principally for epicurean travellers abroad' is the wordplay.
'principally' says to take the initial letters.
The first letters of 'for epicurean travellers abroad' is 'FETA'.
(Other definitions for feta that I've seen before include "A ewe's, goat's milk cheese" , "Type of cheese" , "Soft Greek cheese" , "Greek dairy product" , "Low-fat cheese" .)
