Season a few to make them tasty (11)
I believe the answer is:
flavoursome
'make them tasty' is the definition.
I can't judge whether this definition defines the answer.
'season a few' is the wordplay.
'season' becomes 'flavour' (synonyms).
'a few' becomes 'some' (both can mean a small amount of something).
'flavour'+'some'='FLAVOURSOME'
'to' is the link.
Can you help me to learn more?
(Other definitions for flavoursome that I've seen before include "full of zest?" , "with loads of smack" .)
