Taste something cheap and something dear? (7)
I believe the answer is:
snippet
'taste' is the definition.
(only a small amount)
'something cheap and something dear?' is the wordplay.
'something cheap' becomes 'snip' (snip can mean a bargain).
'and' is a charade indicator (letters next to each other).
'something dear?' becomes 'pet' (as in a pet project).
'snip'+'pet'='SNIPPET'
(Other definitions for snippet that I've seen before include "Small extract" , "Brief extract" , "A cutting" , "Bit (of info?)" , "excerpt of literature?" .)
