I believe the answer is:
chef
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">kitchen leader</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for chef that I've seen before include "Key kitchen worker" , "One who prepares courses" , "member of kitchen staff" , "who has a set of knives?" , "French master" .)
