Melt butter in a large frying pan over medium-high heat. Add chicken strips and cook until well-browned, about 3 to 4 minutes.
Add cumin, turmeric, hot pepper flakes and garlic. Cook for about 3 minutes, stirring frequently.
Add chicken broth and bring to a boil, then reduce heat to medium. Cook for about 10 minutes, stirring occasionally.
Slowly add sour cream and simmer for another 4 minutes, or until chicken is thoroughly cooked. Garnish with fresh parsley, and serve with your favourite side dishes.
