This restaurant-worthy treat has a secret: Its rich, chocolatey ganache is butter-free and made with 15% cream instead of the full 35%. Despite the lower fat content, it doesn't compromise on flavour or on that smooth, melt-in-your-mouth consistency. Shards of pistachio dacquoise (nut meringue) add a welcome layer of texture, while the tartness of the orange syrup and the hit of acid from the orange segments bring balance and brightness.
