Grind up salt with a kitchen utensil (7)
I believe the answer is:
spatula
'kitchen utensil' is the definition.
(I know that Spatula is a type of food turner)
'grind up salt with a' is the wordplay.
'grind' is an anagram indicator (I've seen this in other clues).
'with' indicates putting letters inside.
'up'+'salt'='upsalt'
'upsalt' is an anagram of 'sptula'.
'sptula' going around 'a' is 'SPATULA'.
(Other definitions for spatula that I've seen before include "Kitchen implement with a flat, blunt blade" , "Broad spoon" , "Implement for mixing/spreading" , "Food turner with flexible blade" , "flat mixer" .)
