I looked up Piri-Piri (Portuguese and South African) and made up about a cup using the following spices. (I used a spice blender to mix the oregano and parsley flakes in.) The recipe for two breasts calls for 1/4 ounce of Piri-Piri.
2 T. each of sugar, paprika, onion powder, garlic powder, ground coriander
1 T. each salt, dried oregano, and dried parsley.
2 tsp. each of ground ginger and cardamom
1 tsp. each of smoked paprika and cayenne pepper
Place in an airtight jar.
Note! You can use more cayenne if you'd like. If you use very red paprika and cayenne, your blend will be nice and colorful!
