My dear friend Knoxy inspired this recipe. She asked me if I had ever had elderflower liqueur and when I said no, her eyebrows rose in surprise, and she soon brought me a bottle to experiment with in cooking. Boy, am I glad she did. With its sweet floral top note and a subtle musky base note, my taste buds went bonkers and my mind raced with culinary ideas. Blancmange, which literally translates from French as “white food,” has been a very popular molded dessert for centuries. It is traditionally flavored with orange flower water, but elderflower gives it a whole new dimension.
