Preparation

• To make the brine, combine the salt, sugar, water, lemon, peppercorns, mustard seeds, and coriander seeds in a medium saucepan and heat over medium heat, whisking occasionally, until the salt and sugar dissolve, about 5 minutes. Transfer to a medium-large bowl, add the coffee, and refrigerate until cool, about 15 minutes. Put the chicken breasts in the brine and set a pot lid or small plate on top to keep them submerged. Refrigerate them in the brine for 2 to 3 hours.
• Heat a gas grill to high or prepare a hot charcoal fire. If using wood chips with a gas grill, pile them in the smoker box or in a smoker pouch (seeHow to Add Smoke to a Gas Grill). Run your grill on high until you see smoke. If using a charcoal grill, toss the wood chips directly onto the hot coals.
• 排干鸡肉，用纸巾干燥。用融化的黄油或油轻轻刷两面。将乳房与炉排的棒上的烤架上以45度的角度排列在烤架上。烧烤直到有大约2分钟的烧烤痕迹，然后将它们旋转90度（以获得十字架烤架），然后继续烧烤2至4分钟。将乳房翻转，煮熟的乳房，它们牢固地触摸，再过4至6分钟。立即服务。
