Ree Drummond turns up the heat for dinner with her sister, Betsy. She makes a stunning Spicy Blackberry Pork Loin with a sticky and savory glaze, a magnificent fiery Baked Pepper Mac and Cheese on the side, and a Mango Chipotle Kale Salad with a smoky, sweet and spicy edge. After all that fire, she shakes up icy Salted Melon Margaritas, the perfect cooling cocktail.
