My grocery store sells a variety of masalas, or spice mixes, marketed for various dishes. For example, there is chicken masala, korma masala, chana masala, goat masala, etc.
Are these packaged mixes intended to be used on their own, as in the entire spice base of the dish comes from the mix? Or are these intended to be used in addition to other base spices such as cumin, coriander, black pepper, and turmeric?
