LEMON BARLEY STUFFING

Steps:

• Preheat oven to 400 degrees. In a large pot, melt butter over medium-high heat. Add leeks and cook, stirring, until softened, about 5 minutes. Add barley and rosemary sprig; cook 1 minute more. Pour in the stock, 1 1/2 cups water and 3/4 teaspoon salt. Bring to a boil over high heat; reduce heat, cover and simmer until barley is tender and most liquid has evaporated, about 1 hour 15 minutes. Check it after an hour. If it is tender but liquid is not absorbed, drain barley in a strainer. Or if liquid has evaporated and barley is still not tender, add a little more water and continue cooking until it is.
• Meanwhile, toss mushrooms with oil, 3/4 teaspoon salt and 3/4 teaspoon pepper. Spread in a single layer on two large baking sheets. Roast, tossing occasionally, until tender and beginning to crisp around edges, 20 to 25 minutes.
• Make chive butter: In a mortar and pestle or mini food processor, mash together the garlic and salt until it forms a paste. Stir in the lemon zest and juice until salt dissolves. Pound or pulse in the chives, then stir in the butter until incorporated.
• Spoon hot barley into a large bowl. Stir in mushrooms, hazelnuts, parsley and chive butter until well combined. Taste and add more salt and lemon if necessary.
