How to Make It
Lightly coat a 9-inch square baking dish with nonstick cooking spray and line with parchment paper, leaving a 1-inch overhang on 2 sides.
In a medium microwave-safe bowl, microwave the chocolate in 30-second bursts for about 1 1/2 minutes, until melted. Using a rubber spatula, stir in the condensed milk, cocoa powder, kosher salt and Cointreau until combined. Microwave for 1 minute, until the fudge loosens slightly. Stir in the pistachios, cherries and ginger until just combined. Scrape the fudge into the prepared pan, smoothing the top with a spatula. Refrigerate until firm, about 45 minutes.
Using the parchment overhang, lift the fudge out of the baking dish and transfer to a cutting board. Sprinkle the top with turbinado sugar and flaky salt, cut into 1-inch squares and serve.
