A spicy smoked-paprika marinade gives skin-on butterflied chicken a robust flavor. To give the chicken even more flavor, loosen the skin with your hand and spread some of the mixture underneath before grilling.
Which rub to use depends on the food you're preparing. The heartier the food, the stronger the rub should be. A piquant rub, such as this one made with paprika and other spices, is a good match for rich-tasting salmon.
