Foley has an hour to prepare her dish in the racecourse kitchen. She then plates her dessert and is led out for the long walk to the judges as their six severe eyes are fixed on her.
Ray McVinnie is first for a taste. How did Foley come up with inspiration for the idea, he asks? "My mother used to let me into the kitchen to make desserts because she didn't trust me to make dinner," she replies. "If I mucked up dessert there was still food for the family."
Next is Josh Emett, asking technical questions about the dish. Is the macadamia a straight substitute for almond, which is the normal ingredient in a frangipane tart?
No, she has added more macadamia and tweaked the vanilla content to compensate.
Simon Gault approaches finally. "High praise from the boys," he says, maintaining a poker face.
