Difference Between Tomato Sauce and Tomato Ketchup
In the US, ketchup is prepared with tomatoes, sugar, vinegar / acetic acid and spices. It is used as a dressing or table condiment. Ketchup is cold and is never heated as a rule.
Tomato Sauce on the other hand, is made from tomatoes, oil, meat or vegetable stock and spices. Vinegar is not usually used. Sauces are generally served hot. Most manufacturers insist that ketchup is made with spices while sauce is generally made without spices.
Catfish Effect
'Catfish Effect' is a term used in human resource management to describe how groups are motivated by the addition of a strong competitor. The phrase comes from the practice of Norwegian fisherman, who add a single catfish into their haul of live sardines. In this way, the sardines swim vigorously to avoid contact with the catfish, and can be brought to market while still alive, thus fetching a higher price.
