Mix up salt with a kitchen utensil (7)
I believe the answer is:
spatula
'kitchen utensil' is the definition.
(I've seen this before)
'mix up salt with a' is the wordplay.
'mix' indicates anagramming the letters.
'with' indicates putting letters inside.
'up'+'salt'='upsalt'
'upsalt' anagrammed gives 'sptula'.
'sptula' going around 'a' is 'SPATULA'.
(Other definitions for spatula that I've seen before include "Thin-bladed kitchen tool" , "Tool with broad flexible blade for spreading and mixing" , "Implement with broad blunt and often flexible blade" , "Kitchen utensil" , "Flexible knife-like instrument" .)
