How to Make It
In a medium saucepan, warm 2 tablespoons of the oil over moderate heat. Add the mustard sees and cover the pan. When the seeds begin to pop, remove the pan from the heat and wait until the popping has stopped, about 30 seconds. Uncover the pan; the seeds will be dark gray.
Return the pan to the heat and add the onion. Cook over moderate heat, stirring, until softened but no browned, about 5 minutes. Add the garlic, ginger, turmeric, honey and cayenne and cook, stirring, until fragrant, about 3 minutes. Add the chicken stock and boil over high heat until reduced by half, about 5 minutes. Add the créme fraîche and cook over moderately high heat, stirring occasionally, until the sauce lightly coats the back of a spoon, about 4 minutes. Season the sauce with kosher salt and black pepper.
Remove the tender from each piece of chicken. Cut the chicken breasts in half crosswise and lightly pound all the pieces to an even thickness. Season them with salt and black pepper, then dredge lightly in flour, shaking off the excess.
In a large skillet, heat the remaining 3 tablespoons of oil. Add the chicken in batches and brown over moderately high heat, about 2 minutes per side. Arrange the chicken on plates or a platter. Spoon the sauce over the top and sprinkle with the parsley. Serve at once.
