Mix the Ingredients: Combine all the spices in a mixing bowl. Use a pestle and mortar to pound the ingredients until they become powdery and evenly distributed.
Prepare the Marinade: Rub the mixture generously over your chosen meat or fish.
Marinate: Allow the meat or fish to marinate for 2-3 hours if you can, but if you're in a hurry, 30 minutes will just about do it.
