Brined Turkey Breast with Spanish Spice Rub

For the Turkey and Oranges: 

1. Place water in a large bowl or plastic container. Whisk in salt and sugar and let sit 5 minutes to dissolve. Add the turkey breast, cover, and let sit in the refrigerator for 45 minutes. 
2. Heat griddle to medium-high. Remove turkey from the brining solution, rinse well under cold water and pat dry with paper towels. Rub the skin side of the turkey with the rub (see below for recipe). Using tongs, dip paper towels into the oil and oil the grates of the griddle. Place the turkey on the griddle, rub side down and cook until slightly charred and a crust has formed, about 4 to 5 minutes. 
3. Reduce the heat to medium, turn the turkey over and continue cooking, with the lid closed for 30 to 40 minutes or until an instant-read thermometer inserted into the center of the breast registers 70 degrees C (the temperature will continue to rise off the heat). Remove from the heat, loosely tent with foil and let rest 10 minutes before slicing. 
4. Slice into 1 1/4 cm thick slices. 
5. While turkey is resting, brush the cut side of oranges with oil and place cut side down on the griddle and cook until slightly charred. Ladle sour orange sauce onto a platter and top with the sliced turkey. Garnish with griddled oranges and parsley leaves. 

 For the Spice Rub: 

1.  While turkey is brining, whisk ingredients together in a bowl. 

 For the Sour Orange Sauce: 

1. Heat the oil in a medium saucepan over medium-high heat on the grates of the griddle. Add the onions and cook until soft. Add the garlic and cook for 1 minute. Add the orange juice, zest, and lime juice and cook until the mixture is reduced to about 125 ml. Stir in the honey. 
2. Add the chicken stock and cook until it's reduced to a sauce consistency, about 500ml. 
3. Strain the sauce into a bowl, whisk in the butter, and season with salt and pepper. Stir in the thyme and parsley and serve hot.
