A rub is a dry spice mixture, usually consisting of salt, sugar, herbs, and various spices. The term comes from the English verb "to rub," meaning "to rub in." This is exactly what happens: The mixture is rubbed into meat, fish, or vegetables before grilling or smoking. The goal is to give the grilled food an aromatic, flavorful, and often crispy crust, while developing intense flavors on the surface.
Difference between rub and marinade
A rub is dry and is massaged directly onto the grilled food without oil or other liquid. A marinade, on the other hand, is liquid and usually consists of oil, acids, spices, and herbs, in which the grilled food is marinated.
The rub primarily creates an aromatic crust and an intense surface on the outside, while the marinade tenderizes the meat and brings the flavor to the inside.
The effect also differs: The rub primarily works on the surface, while a marinade penetrates the meat through acids or enzymes.
Another difference lies in storage: Rubs have a long shelf life and can be easily stored, whereas marinades have to be freshly prepared.
Whether rub or marinade – the right preparation is what matters for the taste!
