Cook’s Note: Ina decorated the cake with a chevron pattern in this episode. For the icing, she mixed 1 3/4 cups confectioners’ sugar with 3 tablespoons water in a small bowl and placed the mixture in a pastry bag. Using a small round pastry tip, she piped 6 equally spaced straight lines of icing across the top of the cake. Using the back side of a small knife, she lightly drew 7 evenly spaced straight lines in the ganache perpendicular to the lines of icing, alternating the direction for each line.
