In a large bowl, whisk together the yogurt, garlic, ginger, garam masala, chili powder, fenugreek, garlic powder, cumin, onion powder, paprika, salt, and turmeric until smooth.
Add the chicken to the bowl, and toss it in the marinade. Cover with plastic wrap, and place it in the fridge for at least one hour to marinate or up to overnight if you can.
- Adjust the taste to your liking, adding more or less spice to suit your needs.- The longer the chicken can sit in the marinade, the better the flavor.
