The "ketchup" used for cooking is raw and has not been carefully processed.

Sandwiches, French fries and the like use "ketchup", which is cooked and then finely processed.

Ketchup can't be eaten directly, but sauce can.

There is a certain difference in price between the two. Ketchup is cheap, but sauce is more expensive.

The sauces in the supermarket are all packed in small bags like McDonald's, and there are more than a dozen kinds.

If it's cooking, you have to use ketchup, tomato and chicken slices with water or something. The ratio of ketchup to water is

1:0.75

That's the best

3:2
