Fully cooked (4)
I believe the answer is:
done
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">fully cooked</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for done that I've seen before include "Finished or ended" , "agreed" , "(Of food) well cooked" , "Concluded (and dusted?)" , "Cooked; carried out" .)
