Taste dish outside Austria (6)
I believe the answer is:
palate
'taste' is the definition.
(palate can mean an ability to distinguish tastes)
'dish outside austria' is the wordplay.
'dish' becomes 'plate' (plate is a kind of dish).
'outside' is an insertion indicator (some letters go outside others).
'austria' becomes 'a'.
'plate' going around 'a' is 'PALATE'.
(Other definitions for palate that I've seen before include "relish" , "Sense of taste at roof of mouth" , "part of trap" , "having ability to appreciate good food" , "Liking" .)
