Is soya sauce the same as ketjab?

No, soy sauce and ketchup are not the same thing.

* Soy sauce is a fermented sauce made from soybeans, wheat, salt, and water. It has a salty, umami flavor and is used as a condiment or flavor enhancer in many Asian cuisines.

* Ketchup is a sweet and tangy sauce made from tomatoes, vinegar, sugar, and spices. It is commonly used as a condiment for dishes such as fries, burgers, and hot dogs.

While both are sauces, they have very different ingredients, flavors, and uses.
