Caramelized Brussels Sprouts with Dark Cherry Sauce and Hazelnuts

1. Preheat oven to 400 F. Trim the ends off the Brussels sprouts and remove any discolored or damaged outer leaves. Cut them in half lengthwise, or in quarters if they are very large.
2. Place the Brussels sprouts on a large rimmed baking sheet. Drizzle the melted clarified butter on top and sprinkle on the salt and pepper; toss to combine.
3. Roast the Brussels sprouts until golden and crisp outside and tender inside, about 20 to 30 minutes, flipping once halfway through.
4. While the Brussels sprouts roast, make the cherry sauce. Add the cherries, water, balsamic, soy or tamari, and mahlab to a small saucepan over medium heat. Cook until the cherries are softened but not mushy and the sauce is thickened, about 4 to 5 minutes, swirling the pan occasionally.
5. Pour the Brussels sprouts into a serving dish and top with the cherry sauce and hazelnuts. Serve immediately.
