I didn't think it unfair?
When seeing "mush", it didn't take me to come up with "schmaltz"
And it is given in Bradford's under "mush"....I have just checked.
I don't doubt that there is a definition somewhere but how many dictionaries do we need to consult before finding it? It should be possible to solve a clue from the fodder, not by working backwards.
Which def. are you unhappy with ? I did not consult any dictionaries until you asked for clarification. I consider all the clues were fair and solvable from the fodder provided.
