Your great-grandmother probably used rubs in the form of butter, salt, pepper, garlic and herbs on the Sunday roast! All that has happened since then is that a verb has been turned into a noun! Essentially a rub is a beautiful combination of herbs & spices that adds loads of flavour to your recipes.
The salt and sugar content in rubs is there to draw out some moisture from the meat, so that the flavours from the rub melt and penetrate the flesh of the meat. When heat is applied the rub acts as a seal and all the infused flavours remain absorbed in the meat. NoMU prefers to keep sodium and sugar levels low, so you might need to add more to suit your taste. Be cautious however as too much salt can draw out too much moisture and too much sugar will burn.
Rubbing with NoMU rubs is incredibly easy and a great way to produce delicious meals which bring a great sense of reward! With rubs you can be creative not only in flavour but also in method as you can roast, fry, bake or barbeque!
