<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">mix together</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 blend that I've seen before include "Intermix" , "Combine together" , "Coalesce" , "Mingle" , "union" .)
