As any five-year-old will tell you, sweet is a taste that's easy to love, but really, it's only a first step into the range of flavours and textures that make a great dessert. This berry tart has less than two tablespoons of granulated sugar. Instead it relies on juicy, tart berries, slightly salty ricotta cheese, a wisp of buttery crust and a drizzle of warm, smoky syrup for complexity and all-around deliciousness.
