Select the option that best completes the analogy: Sieve : Sift :: Ladle : ?

The relation is tool : the action the tool is made to perform. A sieve is the implement used to sift. A ladle is the implement used to serve out liquid food, so the relation gives 'Serve'. 'Stir' is the tempting answer because a ladle can be pushed about in a pot, but stirring is the work of a spoon or spatula, not the purpose the ladle is shaped for; grinding belongs to a pestle and cutting to a knife.
