Prepares one salsa, but not all year (8)
I believe the answer is:
seasonal
'prepares one salsa but not all year' is the definition.
I can't judge whether this defines the answer.
'prepares one salsa' is the wordplay.
'prepares' is an anagram indicator (I've seen 'prepared' mean this).
'one'+'salsa'='onesalsa'
'onesalsa' anagrammed gives 'SEASONAL'.
Can you help me to learn more?
(Other definitions for seasonal that I've seen before include "Varying according to time of year" , "depending on the month" , "For a particular period" , "not wanted all year" , "Occurring at particular times of the year" .)
