<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">a soft cheese</span>' is the definition.<br/ ><span class="explanation-format__explanation">(brie is a soft cheese)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for brie that I've seen before include "French 8 across" , "cheese-producing region" , "Bergamot-flavoured tea" , "French produce" , "Soft, creamy French cheese" .)
