Marinades, made with wet ingredients, including wine, vinegar, herbs and spices, are used to either marinate or inject meats and vegetables. They usually sit for a few hours to overnight to infuse the flavors. Using marinades enhances tenderness and moistness of meats.
Rubs, made with dry ingredients, also include spices and herbs. They are hand rubbed on the food, which helps draw out unwanted water and permeate it with flavor. Using a dry rub gives your meats a tasty, crunchy outer coating (called Bark) that is enhanced by the smoke.
