Rush to get a beater (5)
I believe the answer is:
whisk
'a beater' is the definition.
(thesaurus)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for whisk that I've seen before include "Whipping utensil" , "Kitchen utensil" , "Egg beater" , "Beat to a froth" , "Food mixer" .)
