Sauces provide flavour, moisture, and a contrast in texture and colour. They may also serve as a medium in which food is stored. Sauces are the real delicacy to amplify the taste of any food. Sauces may be used for sweet or savoury dishes.
Sauces of specific flavour require vegetables like tomato or green chilly which are crushed and ground and then liquified. Additional herbs are added to enhance the taste of that particular sauce.
