The Sauces are designed, made and packaged specially for the restaurants, by such the costs have been reduced as much as possible. Naturally if by using the Sauces one can offer better tasting dishes then the competition then this is the best way. Furthermore, one can market these dishes as signature or speciality dishes and can charge a higher price than normal dishes. Another tip: the content of the aluminum packaging is targeted for 4-person dishes. To prepare a smaller dish, you may use half of the content to reduce the costs.
