A new pairing of constructors brings us a different variation on the remove letters theme. I wonder if Kathy and Lewis got together after a crossword tournament encounter? We have a take out two letter theme to allow for an amusing result, clued appropriately. I believe AD has been used before as the basic Bigram of constructors, but no example comes to mind. Of course, my mind has a mind of its own.
While this appears to be a first-time collaboration, it seems to be a seamless effort. Humor and variety. It has some sparkle with
AERIALS, AMASSED, ANNE RICE, DEERSKIN, PINENUTS and, SOUL FOOD.
Time for the theme.
