I call this herb and spice rub North African because, besides the classic oregano and rosemary, it contains Tunisian and Moroccan spices such as caraway, cumin, and turmeric. In addition, it is spiked with harissa, the ubiquitous hot pepper paste that is to Arab North Africa what chile oil is to Asia. Use the same spice mixture to rub poultry, beef, or pork two to three hours before grilling and leave at room temperature. Or you can mix 3 tablespoons of this rub with 3 tablespoons yogurt and baste chicken breasts or legs or skewered lamb and pork before grilling. Better yet, leave in the spicy yogurt marinade in the refrigerator overnight.
