Mix in the chili flakes and sesame seeds, transfer to a heat-proof bowl. In a large skillet, heat the olive oil and chicken, over medium heat. Cook the meat, breaking it up as it cooks, until the chicken is browned, about 5 minutes. Add the curry paste, soy sauce, and 1/3 cup water. Reduce the heat to medium and simmer until the sauce has thickened around the chicken, 5 minutes. Stir in the pickled ginger and a splash of the liquid in the jar.
